Tag to be used with the master branch of atlas/athena.
Update(s) since 2.0.128:
- Retired the atlas_install_headers(...) function, making its use an error;
- Made the projects detect relocation problems during installation;
- Added the DEPENDS keyword to atlas_add_test(...) to conveniently declare dependencies between tests;
- Made it possible to detect the exact version of the found python modules that provide a __version__ variable;
* Made Findmccabe.cmake, Findpycodestyle.cmake and Findpyflakes.cmake report their exact versions;
- Made sure that libffi would be set up correctly for the Python module builds;
- Tweaked PyModules to work correctly specifically with LCG_101.
