One usually do:

find_package(PythonLibs)
instead of:
include(FindPythonLibs)

include(FindPythonLibs) may not be enough:
you seem to be missing something like:

target_link_library(<your_target> ${PYTHON_LIBRARIES})

Same for FindThreads.

find_package(Threads)

however I dont' know that one works because the FindThreads.cmake
module does not seem to define THREADS_LIBRARIES
in order for you to
target_link_library(<your_target> ${THREADS_LIBRARIES})

May be the author of FindThreads may help us with the usage of this module?

compare the link command used by CMake and te one you use in your makefile.

make VERBOSE=1

with CMake generated makefile should show you the full link line.
