"exec(\"import sys\\ntry:\\n  import numpy\\nexcept:\\n  
sys.exit(0)\\nsys.exit(1)\")"

This seems to be great to check that numpy exists! You're probably missing a variable somewhere ;)

Hello everyone,

I wrote a short macro for one project I work on to verify at configuration time that a python library is available on the system on which the project is configured. I have attached a patch to potentially integrate this new macro to CMake. I saw other people doing similar things in other projects, so it might be of interest to the community.
Hope this helps,

Francois
