Comment configurer CMake pour utiliser des modules d'une lib qu'on a créée ?

Salut, j'essaie d'utiliser des modules cxx d'une lib que j'ai créé avec CMake/Clion et clang mais je ne sais pas comment configurer le projet pour le faire compiler. Mes fichiers de configurations CMake sont sur mon repo : https://github.com/LaurentDuroisin7601/ODFAEG (branche master) J'ai essayé avec msvc mais ça n'a jamais compilé et sur linux non plus :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part
