CMake version 2.8 does not recognize Python 3.4

[organman91]

Adding

set(Python_ADDITIONAL_VERSIONS 3.4)

to the beginning of cpp/CMakeLists.txt corrects this issue.

Alternatively, CMake 3 could be a (more clearly specified) requirement.

Or add version 3.4 to the list in (Ubuntu 14.04):

/usr/share/cmake-2.8/Modules/FindPythonLibs.cmake (line 41)
/usr/share/cmake-2.8/Modules/FindPythonInterp.cmake (line 36)

If cmake 3.0 is available in all distros that also have the other dependencies (such as recent versions of gcc and/or g++, libopusfile, ...), there's no reason not to just bump the required cmake version to that version instead of applying hacks. Any feedback on that (I guess Debian stable is out anyway, but what about the various versions of Ubuntu, Fedora, ...)?

[organman91]

On Ubuntu 14.04 the latest available version is 2.8.12 (unless there's a suitable backport).

set(Python_ADDITIONAL_VERSIONS 3.4) it is, then. Though I believe it belongs into python.cmake rather than the cpp.cmake :P
