Add a core function of the build system, responsible for including the
specified component identified by name, into the build
process.
Currently, the non-project components written in cmakev1 are ignored and
not evaluated with the add_subdirectory command because there are no
shims for the cmakev1 API yet. However, this allows for the evaluation
of project components written using the cmakev2 approach, which is
closer to the native CMake usage.
