Sorry, I have applied the patch but then revert the commit since it introduces some troubles when a user install ViSP in a non common location such as /usr.
This is the case for example in ros::vision_visp/visp where ViSP is installed in ros::vision_visp/visp/install folder. In that case visp.pc used by pkg-config was not found until the user set PKG_CONFIG_PATH in a right way. It may be possible to do that automatically with ros, but I haven't investigate enough. 

Thomas, attached is the CMakeModules/visp-config.install.in file that handles the multi arch support.

Hope it helps.
