I cannot compile the examples out of the latest commit (ad7bc01) on my Lubuntu 15.04 machine.

$ gcc --version
gcc (Ubuntu 4.9.2-10ubuntu13) 4.9.2

And the build log:

This should insure that both the PythonLibs and PythonInterp points to
the same python version.

Without this, the Python library and interpreter might not match version.
For example, if both Python 2.7 and 3.4 is installed, PythonLibs will
find /usr/lib/x86_64-linux-gnu/libpython3.4m.so while
PythonInterp will find /usr/bin/python2.7 (at least on Ubuntu 14.04).

When PythonLibs and PythonInterp don't point to the same Python version,
the examples will all fail:
