USE_PYTHON_3=OFF doesn't work

It still linked to python2. I have both installed on FreeBSD.
There can be many python versions installed. You should have a cmake variable which accepts the python executable, and then you should read everything else from it.

Giving the status of python2, I am not going to spend more energy into building against that. Should probably get rid of USE_PYTHON_3 altogether.

There still can be a problem in selection of python-3.5 vs. python-3.6 for example.

It's something worth doing at some point, but requires careful testing. At the moment I am happy that the lot builds on all the various platforms; I would like to avoid introducing changes which are likely to break the build on one of them.

I am not saying that this is urgent, it's rather something to keep in mind.
Once you have a patch I will be happy to test it. FreeBSD might be the best platform to test it because one can easily install all possible python versions at the same time.
Currently, this is a source of potential incorrectness in the FreeBSD port.

Python 2.x is no longer supported (hasn't been for some time) so I am closing this.
