Use PROJECT_*_DIR instead of CMAKE_*_DIR to support subproject builds

Replace CMAKE_[SOURCE/BINARY]_DIR usage with PROJECT_[SOURCE/BINARY]_DIR to
support subproject builds. This helps make the project usable as a subproject
(e.g. via add_subdirectory or FetchContent) without polluting the parent build tree.
