The solution to the problem should not be found in the python components, but rather in the cmake compilation system, to solve the problem it is sufficient to add the two directives find_package(PythonInterp 2.7 REQUIRED), and
find_package(PythonLibs 2.7 REQUIRED) to CMakeLists.txt file of the libarea source pack, perhaps immediately after the endif(NOT BUILD_TYPE).

endif(NOT BUILD_TYPE)
--- here is good ---------

find_package(PythonLibs 2.7 REQUIRED)
