Yea this is totally strange that it finds python libs in the regular
build and not here. Perhaps there is some variable set prior to finding
python libs in the howto thats not set in the main build.

I might suggest that you start deleting things until it works. For
example, start deleting subdir includes (except swig) until it works:

add_subdirectory(include)
add_subdirectory(lib)
add_subdirectory(swig)
add_subdirectory(python)
add_subdirectory(grc)
add_subdirectory(apps)
add_subdirectory(docs)

or move around the call to find_package(PythonLibs) higher up in the top
level Cmakelists until it works.
