Visual 2015 generator doesn't propagate include directories like others
We have many targets. The include directories are added with target_include_directories(target PUBLIC ...) And target are link with target_link_libraries( ${project_name} PUBLIC ...) or (without PUBLIC)
While it generates a compilable solution with Visual 2013 it doesn't with Visual 2015.
It seems that it's the includes of the dependencies of a dependency which are not propagated beyong.
It's the same with CMake 3.6.2 or 3.7 rc2
