cmake doesn't find python3-dev library

[Petr]

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.

this might be related to http://www.cmake.org/Bug/print_bug_page.php?bug_id=13794

Note, this problem happens only on ubuntu (in my case trusty) in debian it works just fine

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.
