You should set "CMAKE_SYSTEM_NAME", not "CMAKE_SYSTEM" to "Linux". If you really set CMAKE_SYSTEM instead of CMAKE_SYSTEM_NAME, this will fix your problem (after a quick look it seems install_name is really only set in the Modules/Platform/Darwin*.cmake files, which should not get loaded if CMAKE_SYSTEM_NAME is set to Linux).
