#574 Numpy detection by cmake fails if python3 is the default
On systems where /usr/bin/python is python3 (Manjaro, Arch), the FindNumpy.cmake script fails to work even if python3-numpy is installed because of a syntax error in the inline python call:
python -c 'import numpy; print numpy.get_include()'
This appears to use a syntax that is no longer supported (sorry I'm not a python programmer).
A temporary work-around is to force the use of python2 by using "-DPYTHON_EXECUTABLE=/usr/bin/python2" in the cmake command line.
Actually there may be other python 2/3 issues as cmake was also detecting the python3 executable and the python2 libraries.
Closing here as this problem is now referenced from a github report: https://github.com/gnudatalanguage/gdl/issues/91
