Summary:                    Updating GIT_SUBMODULES of already cloned repo will
not init them
Description: 
If project added via ExternalProject_Add that specifies GIT_URL and
GIT_SUBMODULES was already cloned, adding new module to GIT_SUBMODULES will not
cause cmake to fetch it. Instead it will fail with the following error:

Submodule path 'Resources' not initialized
Maybe you want to use 'update --init'?

Steps to Reproduce: 
1. Add ExternalProject_Add that specifies both GIT_URL and GIT_SUBMODULES
2. Generate and build
3. Append another submodule to GIT_SUBMODULES
4. Build again
