When a component's manifest declared a managed dep `<ns>/<name>` and the
project had a local `components/<name>` shadowing it, configure failed
with `IDF: Failed to resolve component '<ns>__<name>'`.
cmakev1 does a project-wide injection so the manager's _choose_component
sees every component name in known_components and rewrites the
namespaced dep to its locally-shadowing short name. cmakev2 invokes the
manager per component with a single-component requirements file, so
known_components has only one entry and the rewrite cannot fire --
`<ns>__<name>` is written verbatim into MANAGED_REQUIRES and the
force-include at component.cmake:995 aborts.
Seed the per-component requirements file with one __COMPONENT_SOURCE
entry per discovered component so handle_project_requirements() builds
the same known_components list cmakev1 produces. The seeded entries are
inert on the cmake side -- the __component_set_property shim ignores
__COMPONENT_SOURCE -- they exist purely to feed the manager's rewrite.
Add a regression test in tools/test_build_system/buildv2/test_component.py.

The __init_project_configuration() function in cmakev2's project.cmake
unconditionally applied app-level compiler optimization flags based on
CONFIG_COMPILER_OPTIMIZATION_* Kconfig options. When the bootloader
subproject was built with cmakev2, these app-level flags leaked into the
bootloader compile command alongside the correct bootloader-specific
flags from CONFIG_BOOTLOADER_COMPILER_OPTIMIZATION_*.
For example, with the default configuration (app: DEBUG, bootloader:
SIZE), the bootloader received both "-Og -fno-shrink-wrap" (from app
config) and "-Os -freorder-blocks" (from bootloader config). While GCC
uses the last -O flag (-Os wins), the stray -fno-shrink-wrap persisted.
Introduce a SET_COMPILER_OPTIMIZATION build property that defaults to
YES when unset. Subprojects that manage their own optimization flags
(like the bootloader) can set this to NO before calling
idf_project_init() to prevent the default optimization flags from being
applied. This keeps project.cmake generic without requiring it to know
about specific subproject types.

Commit f62f45cf5c changed target_add_binary_data to resolve the
embedded file path relative to the component directory by using
idf_component_get_property to obtain the COMPONENT_DIR. This fixed the
path resolution when target_add_binary_data is called from
idf_component_include, which runs outside the component's directory
context.
However, target_add_binary_data can also be called directly from a
project's CMakeLists.txt with a non-component target, e.g.
target_add_binary_data(app.elf ...) as done in
examples/security/security_features_app. In this case,
idf_component_get_property fails because the target is not a component.
Fix this by moving the path resolution to idf_component_include, where
the embed file paths from EMBED_FILES and EMBED_TXTFILES component
properties are resolved to absolute paths relative to COMPONENT_DIR
before being passed to target_add_binary_data. This way,
target_add_binary_data receives already absolute paths from
idf_component_include and can use plain get_filename_component(ABSOLUTE)
for direct calls, which correctly resolves relative to
CMAKE_CURRENT_SOURCE_DIR.

Add a GENERATE_SDKCONFIG build property that controls whether kconfgen
writes the sdkconfig file (--output config) during the configuration
step. It defaults to 1 (enabled).
When building the bootloader as a subproject, the set of components
(and their Kconfig files) differs from the main project. Running
kconfgen with --output config in this context rewrites the main
project's sdkconfig. Even when the content is identical, the timestamp
update causes ninja to detect sdkconfig as newer than build.ninja
outputs (e.g. cmake_install.cmake), triggering an infinite CMake
re-run loop.
Setting GENERATE_SDKCONFIG to 0 in a subproject prevents this,
matching the behaviour of cmakev1's __OUTPUT_SDKCONFIG property.

Add the PROJECT_COMPONENTS_SOURCE build property to control how project
components are categorised during component discovery. By default it is
set to "project_components" (priority 3 - highest), preserving the
existing behaviour.
Setting it to "idf_components" (priority 0) before calling
idf_project_init() makes the project's built-in components overridable
by user-supplied components through EXTRA_COMPONENT_DIRS (priority 2).
This is needed for sub-projects like the bootloader, whose built-in
components (e.g. main) are provided by ESP-IDF and should be overridable
by user-supplied components placed in bootloader_components/. The
cmakev1 build system allowed this override because it used a
last-one-wins strategy, but cmakev2 uses strict priority-based component
resolution where project_components always win.

In the cmakev2 build framework, the selected toolchain was not
consistently propagated to sdkconfig generation. For clang builds,
this produced a configuration that was incompatible with the clang
toolchain and broke compilation.
Ensure the toolchain selection is observed consistently so sdkconfig
and component configuration reflect the intended toolchain for both
GCC and clang builds.
Made-with: Cursor
When the component manager is disabled via IDF_COMPONENT_MANAGER=0, the
cmakev2 build system still entered the full component manager flow
(__fetch_components_from_registry), which called
__download_managed_component(). That function returned early with
result=0 without creating the expected output file, violating the
post-condition in __download_component_level_managed_components() that
checks result==0 => file exists, causing a fatal error.
Instead of patching the low-level function to write an empty stub file,
this commit properly skips the entire component manager flow when the
manager is disabled:
- Move __init_component_manager() to idf.cmake global initialization
sequence alongside other __init_*() calls, so IDF_COMPONENT_MANAGER
build property is available early.
- Set __SDKCONFIG_ORIG to the real sdkconfig path in __init_kconfig()
as its default value. Previously it was only set inside
__create_sdkconfig_orig_copy() and had a defensive fallback in
__create_base_kconfgen_command(). The default ensures __SDKCONFIG_ORIG
is always valid regardless of whether the component manager runs.
- Guard __create_sdkconfig_orig_copy() with an IDF_COMPONENT_MANAGER
check. The sdkconfig backup exists solely to preserve unknown Kconfig
options from managed components during intermediate kconfgen rounds.
When the manager is disabled, no managed components exist, so the
backup is unnecessary.
- Guard __fetch_components_from_registry() call in project.cmake behind
IDF_COMPONENT_MANAGER == 1. When disabled, only the manifest warning
is issued. No download loop runs, no temp files are created, and no
"Component manager round N..." messages are printed.
- Remove the now-redundant IDF_COMPONENT_MANAGER guard from
__download_managed_component(), since it is only reachable when the
manager is enabled.

This commit introduces a new build property, __OPTIONAL_REQUIRES_MODE,
and uses it to either defer or link immediately, optional requirements
to components that request such linkage via the
idf_component_optional_requires() function in build system v2. The
DEFERRED mode is intended for single-binary projects where in the linking
of optional components happens after the library target is created the
dependency graph is available to the build system, thereby allowing it to
behave like the v1 version of the function.
Introduce a callback mechanism that lets components register CMake
functions to be called at specific points in the build lifecycle.
Currently, this framework only supports registering callbacks to be
called after the executable target is created, i.e, the POST_ELF phase
of the build but before the binary target is created.
Add idf_build_get_compile_options() to aggregate COMPILE_OPTIONS,
C_COMPILE_OPTIONS, CXX_COMPILE_OPTIONS, and ASM_COMPILE_OPTIONS build
properties with generator expressions. Replace internal
__get_compile_options(OUTPUT ...) usage in idf_component_register and
idf_component_include with the new public function.
When MAPFILE_TARGET is used in idf_build_executable, add the linker
--cref option so the cross-reference table is written to the map file
instead of stdout. Remove the global -Wl,--cref from default link
options in project.cmake so cref is only applied where a map file
is requested.
Currently, embedded files can be added in two ways. First, by calling
the `target_add_binary_data` function directly within a component.
Second, by passing `EMBED_FILES` or `EMBED_TXTFILES` to
`idf_component_register`, or in cmakev2 by setting the `EMBED_FILES` or
`EMBED_TXTFILES` component properties.
The source file for an embedded file is generated using
`add_custom_command`. When the embedded file is added directly in the
component's CMakeLists.txt file by using the `target_add_binary_data`
function, the `add_custom_command` command is evaluated in the same
directory context where the component target is created. As a result,
the generated embedded file can be used automatically as a file
dependency in component's sources.
However, when an embedded file is added via `idf_component_register` or
by setting the component property, the call to `add_custom_command`
inside `target_add_binary_data` occurs after the component has been
evaluated, specifically after the `add_subdirectory` call, within
`idf_component_include`. This means it is not created in the same
directory context as the component's target. In this case, the embedded
file dependency is not added to the component's target, and the embedded
file is not generated. This behavior is described in the
`add_custom_command` documentation [1].
> A target created in the same directory (CMakeLists.txt file)
> that specifies any output of the custom command as a source
> file is given a rule to generate the file using the command at
> build time.
To fix this issue, an explicit custom target for the generated embedded
file is created and added as a dependency of the component's target,
ensuring that the file is generated correctly.

The sdkconfig file may contain configuration options defined in Kconfig
files of managed components. Since kconfgen runs before the component
manager fetches these components, the Kconfig definitions for managed
component options are not yet available. The kconfgen --output config
flag regenerates sdkconfig from kconfiglib's internal state, which only
knows about options with loaded Kconfig definitions. This causes unknown
options (i.e., those from managed components) to be silently dropped
from sdkconfig during intermediate regeneration rounds.
Note that kconfgen's --config flag (used for reading sdkconfig) only
performs deprecated option name replacement and does NOT drop unknown
options. The problem is exclusively in --output config, which writes a
fresh sdkconfig from the parsed Kconfig tree state.
Fix this by introducing a __SDKCONFIG_ORIG build property that provides
an indirection layer for the --config input path:
- Before the component manager runs: __SDKCONFIG_ORIG points to a copy
of the original sdkconfig (build/sdkconfig.orig), created by the new
__create_sdkconfig_orig_copy() function. This copy preserves all
original options, including those from managed components.
- During intermediate kconfgen runs: --config reads from the preserved
copy (so unknown options survive as input), while --output config
writes to the real sdkconfig (unknown options may be dropped there,
but this is harmless since kconfgen always reads from the copy).
- After the component manager completes: __SDKCONFIG_ORIG is reset to
point to the real sdkconfig and __BASE_KCONFGEN_CMD is rebuilt, so
that subsequent operations (menuconfig, save-defconfig, confserver)
read and write the actual sdkconfig file directly.
The flow is:
__create_sdkconfig_orig_copy()
-> __SDKCONFIG_ORIG = build/sdkconfig.orig
__generate_sdkconfig()
-> --config build/sdkconfig.orig --output config project/sdkconfig
__fetch_components_from_registry():
loop:
download_components()
__generate_sdkconfig()
-> --config build/sdkconfig.orig --output config project/sdkconfig
if success: break
endloop
-> __SDKCONFIG_ORIG = project/sdkconfig
-> rebuild __BASE_KCONFGEN_CMD
idf_create_menuconfig() / save-defconfig / confserver
-> uses --config project/sdkconfig (the real file)

The idf_component_optional_requires compatibility function in cmakev2
currently attempts to mimic the behavior of cmakev1 by adding a
dependency only if a component is already included in the build. In
cmakev1, this is handled by checking the BUILD_COMPONENTS list, which is
created during an early evaluation phase. Because cmakev2 removed this
early phase to allow for configuration-based component dependencies, the
build system does not inherently know which components will be part of
the build beforehand. To compensate, the current compatibility function
relies on the TARGET_EXISTS generator expression to determine if a
component should be linked.
This approach poses a problem because generator expressions are not
evaluated until the generation phase, but cmakev2 processes linker
scripts during the configuration phase by recursively scanning targets
linked to a library. Because the scanner does not recognize and cannot
evaluate generator expressions, any component linked optionally through
generator expression is skipped. If that component carries a linker
script, the script is never added to the library interface, resulting in
build failures. Since cmakev2 aims to support multiple libraries, a
component might also exist globally, causing TARGET_EXISTS to evaluate
to true, yet still be missed during a specific library's recursive scan,
leading to the same omission of necessary linker scripts.
To resolve this, the implementation of idf_component_optional_requires
is changed to check if a component is known to the build system in
COMPONENTS_DISCOVERED build property. If so, it is explicitly included
and linked directly via its interface target. While this may pull more
components into a build than the previous generator expression method,
potentially increasing build times, it ensures that dependency trees are
fully visible to the library target scanner. This serves as a practical
middle ground that maintains compatibility with existing components and
ensures build stability. This approach allows for the gradual fixing of
idf_component_optional_requires usage in components for cmakev2, with
the eventual goal of removing its usage in cmakev2 entirely.
This change also fixes cases where idf_component_optional_requires is
used to conditionally add requirements based on configuration options.
In cmakev2, the presence of a configuration option does not guarantee[1]
that a component has been included via add_subdirectory, unlike the
behavior in cmakev1. With this change even constructions like
```cmake
if(CONFIG_VFS_SUPPORT_IO)
idf_component_optional_requires(PRIVATE vfs)
endif()
```
will now work in cmakev2, as the updated idf_component_optional_requires
explicitly includes the required component if it is available to the
build system.

Some components simply return when included in a build for the Linux
target. This is silently ignored in the `idf_component_include`, and the
component interface target is linked as requirement in
`idf_component_register`. This has the side
effect of such components being reported as included, with their
configuration displayed in the menuconfig for included components,
rather than in the submenu for excluded components. For example, the
`bt` component, if added as a dependency in `idf_component_register`,
will be displayed in menuconfig as an included component for Linux
target. The `idf_component_include` function sets the component's
`COMPONENT_REAL_TARGET` property to `NOTFOUND` in such situations. Use
this information when config.env is generated put such components into
excluded submenu. Note that we cannot avoid linking empty component interface
into library, because there might be recursive dependencies and at the
time when the component is included we might not now if it has a real

The IDF_TOOLCHAIN build property is currently incorrectly set to the
default `gcc` value for the linux target, whereas it should be empty.
This misconfiguration causes confusion for components like `soc`, which
adjust toolchain options based on the
IDF_TOOLCHAIN(CONFIG_IDF_TOOLCHAIN_GCC) build property's setting.
When sdkconfig is generated, the IDF_TOOLCHAIN build property is passed
as an environmental variable to kconfgen, and the CONFIG_IDF_TOOLCHAIN
configuration option is set based on this variable. Additionally, the
CONFIG_IDF_TOOLCHAIN_GCC and CONFIG_IDF_TOOLCHAIN_CLANG configuration
options are set accordingly. Subsequently, CONFIG_IDF_TOOLCHAIN_GCC is
used in several places, such as `components/soc/project_include.cmake`,
to configure the toolchain (compiler flags) by invoking functions from
`tools/cmake/toolchain_flags.cmake`, which is included only for
non-linux targets. As a result the configuration fails, because
functions from `tools/cmake/toolchain_flags.cmake` are not available on
linux target.
Since the IDF_TOOLCHAIN cmake cache variable is actually set in the
`tools/cmake/toolchain.cmake` file, the IDF_TOOLCHAIN build property
should be set after the toolchain is initialized in cmakev2's project
initialization. Note that each toolchain file, except for linux,
includes `toolchain.cmake`, which in turn includes
`toolchain_flags.cmake`. This means the IDF_TOOLCHAIN cmake cache
variable is set for every target except linux, because the toolchain
file for linux is empty. As a result CONFIG_IDF_TOOLCHAIN is empty and
CONFIG_IDF_TOOLCHAIN_GCC not set as for cmakev1.

The dependency chain currently tracks component names that are included
recursively with `idf_component_include`. However, these component names
can be ambiguous because a component may be referenced by different
names, such as with a namespace. Additionally, `idf_component_include`

Retrieve the value of the specified component property quickly. The

to identify the component interface target, which keeps the component
properties, and accepts a component name, target, target alias, or
interface. While `idf_component_get_property` uses a cache to identify
the component interface relatively quickly, it is still much slower
compared to the raw `get_property`. The
`__idf_component_get_property_unchecked` function provides a faster way how to
obtain component property if the component interface is already known.

The link flag for generating the map file is currently added globally to

the link map file will be generated by the linker, and a target
specified in the MAPFILE_TARGET option will be created for the map file.
This also splits the idf_project_default macro. Only the
idf_project_init macro needs be called within the global scope, as it

Currently, the `idf_build_generate_metadata` function takes an
executable target as an argument, and the binary name is stored in the
`EXECUTABLE_BINARY` property. This approach is inconvenient because a
single executable might generate multiple binary images, making it
unreliable to store the binary image name in the executable property due
to the N:1 relationship. To address this, pass the binary image target
instead of the executable target to the `idf_build_generate_metadata`
function. This change is facilitated by linking the binary target,
