Path error to openframework

Hi,

We share code with github, my friend can’t build my project. The error is :

Erreur C1083 Impossible d’ouvrir le fichier source : 'Erreur C1083 Impossible d’ouvrir le fichier source : ‘…\…\openFrameworks\3d\of3dPrimitives.cpp’ : No such file or directory openframeworksLib D:\OpenFrameworks\of_v0.9.3_vs_release\libs\openFrameworksCompiled\project\vs\c1xx 1

I can open and build the project of my friend, but he can’t try my project. How can i solve this problem of path please ?
