However, Visual Studio definitely supports a form of varying the source file list of the project between configurations. That's because a source file can be marked as _excluded_ from build for a particular configuration. So the solution CMake could use would be to add all source files from all configurations into the project, but mark them as excluded from [in]appropriate configurations. Petr
