Method SplitFrameworkPath

Source/cmGlobalGenerator.cxx:2834–2878

If the file has no extension it's either a raw executable or might be a direct reference to a binary within a framework (bad practice!). This is where we change the path to point to the framework directory. .tbd files also can be located in SDK frameworks (they are placeholders for actual libraries shipped with the OS)
