kdev-python: finding the required Python library version via CMake

[René J.V. Bertin]

Hi,

The CMake file for kdev-python/parser (v. 1.7.1.5) has the following blurb:

find_package(PythonLibs 3.4.3 REQUIRED)
if ( NOT ${PYTHONLIBS_FOUND} OR ${PYTHON_VERSION_MINOR} GREATER 4 )
    message(FATAL_ERROR "Python 3.4.3 with --enable-shared is required")
endif()

When building in the MacPorts environment under OS X, the only thing that did was picking up an old 2.4.3 (!) framework I'd installed as /Library/Frameworks/Python2.4.framework; after I removed that it stopped finding anything at all. Yet I have python2.7 and python3.4 installed under /opt/local (and in the path) along with all the other dependencies, and cmake itself. The only thing I could but shouldn't have to adapt is letting /opt/local/bin/python be a symlink to python3.4 instead of to python2.7 .

I had a comparable issue with `find_package(PythonInterp 3.0 required)` which I could resolve by hardcoding the PYTHON_EXECUTABLE variable, but I apparently one cannot pull a similar trick with the PythonLibs script.

Is the PythonLibs script supposed to work with multiple parallel python installs (and find the requested one), including on OS X?
Is there a clean way out of this situation?

In addition, what's with the "version 3.4.3 and nothing else" bit? Is that going to change?

Thanks,
R.
