cmake: use PROJECT_{SOURCE,BINARY}_DIR instead of CMAKE_{SOURCE,BINARY}_DIR
CMAKE_SOURCE_DIR refer to the full path to the top level of the current
CMake source tree
PROJECT_SOURCE_DIR refer to the source directory of the last call to the
project() command made in the current directory scope or one of its parents
when ninja is use as a subproject, the build fail because of this.
