Wrong python executable when compiling

When compiling from source on linux it is assumed that /usr/bin/python refers to Python 2. This is true on Debian based distros, but on others (i.e. Arch) /usr/bin/python is Python 3 and Python 2 is at /usr/bin/python2.

You can use the PYTHON_EXECUTABLE CMake option to specify which version of Python to use. Try re-running CMake while adding the following option to the command line:

-D PYTHON_EXECUTABLE=/usr/bin/python2

Let us know if that works.

That does the trick.

Apparently Ubuntu and Fedora also provide /usr/bin/python2, so it should be safe to make that the default path.

The default path for Python is whatever CMake determines to be the location for Python, which is platform-specific. We'll take a look at whether it's possible to tell CMake to look for Python 2 specifically, although I doubt it can be done. In the interest of being platform-agnostic, we probably won't hardcode a path.

At the very least, we'll make it clearer in the ReadMe that you can specify which Python executable to use with PYTHON_EXECUTABLE.
