Testing Orange C with CMake 2

[ghost]

The project I choose to test is https://github.com/aslze/asl.

It's C++11, so it will perfectly fine for Orange C.

CMake configuration completed successfully:

mkdir build
cd build
cmake -DCMAKE_C_COMPILER=occ -DCMAKE_CXX_COMPILER=occ -GNinja ..

But when I actually build it, the build failed immediately with compilation errors:

C:\Work\asl\build>ninja -j1

Building with GCC 14.1 is fine even though there are many warnings.
