Librairie créée avec CMake non réutilisable
Bonjour à tous,
Je développe actuellement une librairie open source multi-plateforme basé sur opencv et pocketsphinx pour des applications robotique.
Sur windows tout marche bien et sur Linux l'installation se passe bien mais pas l'utilisation de la librairie.
Je m'explique: J'utilise CMake pour linker les librairies openCV, pocketsphinx et sphinxbase à ma librairie puis je link ma librairie et les autres librairies à mes exécutables. Cela marche bien quand je compile ma librairie et les codes d’exemples ensemble. Mais lorsque je veux compiler un code d'exemple sans recompiler toute ma librairie cela ne fonctionne pas j'ai à le droit à "undefined reference to" pour chaque fonction de ma librairie utilisant une librairie externe. Comme si le linkage effectuer lors de la création de la librairie statique n'était que temporaire... Comment régler cela ?
CMake pour compiler la librairie et les samples (fonctionnel):
