When using only C++20 modules, CMake project generator creates invalid CMakeLists

Describe Bug

In a project that uses only C++20 modules, the CMake project generator creates CMakeLists.txt with empty target_sources, which results in No SOURCES given to targe: XYZ errors.

Expected Behavior

I'm expecting CMake project generator to fill target_sources with source .mpp files. This allows for IDE to use the CMakeLists file for proper syntax highlighting and other features.

I'm expecting CMake project generator to fill target_sources with source .mpp files. This allows for IDE to use the CMakeLists file for proper syntax highlighting and other features.

cmake now only supports the module for msvc, as a result, xmake can currently only make cmake support modules by generating custom commands. The generated cmakelists.txt should be able to support gcc/clang/msvc.

Of course, for msvc, we could really improve the generated results using target_sources, but I don't have time to improve it at the moment.
