Cmake et chemins

Question

J'essaie de faire OpenVolumeMesh comme décrit dans https://www.graphics.rwth-aachen.de:9000/OpenVolumeMesh/OpenVolumeMesh. Je reçois une erreur:

Cadre de test Google introuvable.

J'ai effectivement téléchargé le cadre et suivi ce qui est chargé de: How to setup Google C++ Testing Framework (gtest) on Visual Studio 2005

et tout le bon déroulement.

a) À quel endroit cmake recherche-t-il gtest? b) Est-ce PATH? Parce que j'ai copié le dossier de google testing framework ici et encore cmake n'a rien trouvé.

Le findgoogletesting.cmake en OpenVolumeMeshis les éléments suivants:

if(GTEST_INCLUDE_DIRS AND GTEST_LIBRARIES AND GTEST_MAIN_LIBRARIES) 
    set(GTEST_FOUND true)

Le vous FindGoogleTest.cmake dit déjà la réponse: vous devez exécuter cmake avec le drapeau suivant ajouté:

cmake -D GTEST_PREFIX=<path/to/gtest> </path/to/OpenVolumeMesh/sources> 

Si vous utilisez le CMake Gui, vous devez cliquer sur 'Ajouter une entrée' et le spécifier ici.
