Sure, but is this doable? CMakeLists.txt files are very complex and border on a Turing-complete language. Does cmake support passing in "-D foo" options and returning a list of dependencies it wants for those options? Because otherwise you'd be back to reimplementing a CMake file format parser / interpreter just to get the list dependencies you need.
