Establish a new distributed CMake architecture with CMake code related to a source directory moving to be in the subdir in its own CMakeLists.txt. In particular, there's now one in ./lib which calls through to ones further down the directory tree like ./lib/plat/xxx, ./lib/roles/xxx etc. This cuts the main CMakelists.txt from 98KB -> 33KB, about a 66% reduction, and it's much easier to maintain sub-CMakeLists.txt that are in the same directory as the sources they manage, and conceal all the details that that level. Child CMakelists.txt become responsible for: - include_directories() definition (this is not supported by CMake directly, it passes it back up via PARENT_SCOPE vars in helper macros) - Addition child CMakeLists.txt inclusion, for example toplevel -> role -> role subdir - Source file addition to the build - Dependent library path resolution... this is now a private thing in the child CMakeLists.txt, it just passes back any adaptations to include_directories() and the LIB_LIST without filling the parent namespace with the details
