workaround for python path and adapt vcs guideline

cyrozap (https://aur.archlinux.org/account/cyrozap/):
"This is the error I got:
CMake Error at /usr/share/cmake-3.3/Modules/FindPythonLibs.cmake:63
(get_filename_component):
  get_filename_component called with incorrect number of arguments
Call Stack (most recent call first):
  wrappers/python/CMakeLists.txt:6 (include)

The root cause of the issue is in CMake's FindPythonLibs on line 63.
When PYTHON_EXECUTABLE is set to "python2" by CMakeLists.txt and
FindPythonLibs tries to get its path a second time, it fails because
the original path returned was empty/NOTFOUND. I'm not sure at what
point it stopped accepting just the executable name and not its full
path, but it must have been some time before CMake 3.3.2 was released
since that's what I'm using.

In any case, the CMake script in the source should be modified to
honor the PYTHON_EXECUTABLE definition if it's set somewhere else--
this patch is just a quick hack to get it to build."
