Interface between eXlibris and Matlib material library ("lite" version can be  downloaded here:
https://git.gem.ec-nantes.fr/MatLib/Lite).

To compile this interface:

include in /my/path/to/matlib/include. Path to sources /my/path/to/matlib/src will also be necessary

3) Add

if(USE_MATLIB)
    set(MATLIB_PATH "/my/path/to/matlib/src will also be necessary"  CACHE INTERNAL "Matlib install path")#
endif(USE_MATLIB)

to the LocalConfig.cmake file. The line "is_not_installed ( USE_MATLIB )" (which is by default activated in the

4) Set BUILD_XINTERFACE_MATLIB and USE_MATLIB to "ON" in the main CMakeLists.txt

5) (Try to) compile !
