J'essaie actuellement de faire fonctionner CMake sur mon système Windows 7 (64 bits). Je veux compiler TagLib pour une utilisation ultérieure avec une application Qt sur laquelle je travaille. Je voudrais la compiler avec MinGW (et non Visual C++ comme dans cette autre question ).
Je télécharge l'installateur (cmake-2.8.3-win32-x86.exe) et l'installe (je choisis également d'ajouter CMake à mon chemin). Je vais ensuite dans le répertoire où se trouve le fichier CMakeLists.txt et j'exécute cmake . . Il me donne alors cette erreur géante.

C:\Users\Joel\Downloads\taglib-1.6.3>J'ai été assez surpris qu'il échoue si durement dès le départ, étant donné qu'il se présente comme un produit multiplateforme.
J'ai essayé de placer INCLUDE, LIB et LIBPATH (variables d'environnement Windows) dans mon répertoire de binaires MinGW ( C:\MinGW\bin ) mais je reçois toujours la même erreur. J'ai également essayé de définir CMAKE_C_COMPILER et CMAKE_CXX_COMPILER à l'emplacement de g++ ( C:\MinGW\bin\g ++).
Quelqu'un sait-il ce qui se passe ici ?
SOLUTION :
Selon la suggestion de tibur, j'ai utilisé l'interface graphique de cmake pour créer les fichiers make. Je suis ensuite allé dans le répertoire taglib et j'ai exécuté mingw32-make.exe pour faire la construction proprement dite.
