Merge pull request #223 from gsomlo/gls-pytrellis-cmake 
ecp5: cmake: Search for pytrellis.so in multiple locations
 2019-02-10 15:43:29 +00:00

1b28bdd121 ecp5: cmake: Search for pytrellis.so in multiple locations 
If a distro-specific "trellis-devel" package is used, the
pytrellis.so library might be located in a dedicated directory,
rather than under TRELLIS_ROOT.

Search for pytrellis.so in a list of directories, then subsequently
use the first match as part of PYTHONPATH.
