Easy switch from python2 to python3

Easy switch from python2 to python3

mdavezac opened this issue 9 years ago · 2 comments

PEP states that in the future the python and python2 command should always point to python 2 and the python3 command should always point to python 3.
Would it be possible to have such a thing in the CMakeCookOff and via this get a switch to configure either for Python 2 or for Python 3.

@tbetcke, that sounds like a good idea.
Currently, I'm just instantiating virtualenvs with either python2 or python3 to test one or the other. But that's more cumbersome than it has to be.

So, it looks like the following does the trick:

cmake -DPythonInterp_FIND_VERSION=2 -DPythonInterp_FIND_VERSION_MAJOR=2 ..

But we could make it easier, either from the cookoff or from bempp.
