CMake: Le compilateur C identification est inconnu

Je suis en train de construire un projet par cmake 2.8.12 avec visual studio 10 de 32 bits de l'architecture. Mais j'obtiens ces erreurs et cmake est impossible de créer le projet. Quelqu'un peut-il svp me suggérer une solution. Merci.

C'est l'erreur de montrer à cmake-gui fenêtre:
