Waltibaba / wrong python version args - with cmake

Last active February 7, 2017 13:46

	http://stackoverflow.com/questions/15291500/i-have-2-versions-of-python-installed-but-cmake-is-using-older-version-how-do

	EITHER:
	find_package( PythonLibs 2.7 REQUIRED ) # if it already has a find_package(PythonLibs)

	OR:
	needed to use python2.7 to compile an older library, but cmake keeps picking up my python3.2 libraries (and executable).
	First, I ran cmake with default options, then edited the CMakeCache.txt file which it generated. I did it this way primarily because I didn't know the proper -D... incantations to cause cmake to get the python library and include paths, etc right in the first place.
	In my CmakeCache.txt, I found lines like this
