Bug Description

If I install python3-dev only, and use it in find_library statement of cmake, it will not find any pythonlibs at all. If I install python-dev (which links to python2.7) cmake will see python2.7 libs, but it still will not be able to find python3 libs, even if I set required version to 3.0.

The problem seems to be that Ubuntu 14.04 installs Python 3.4 by default and the installed CMake version only searches up to Python 3.3. A workaround is to add set(Python_ADDITIONAL_VERSIONS 3.4) before the find_package statement.

CMake 3.0 does search up to Python 3.4.

I think this should be fixed somehow in Ubuntu since there is a inconsistency here. So either CMake should be upgraded or FindPythonLibs.cmake should be patched.
