Visual Studio generator doesn't support /wd options with ClangCL
When using ClangCL it appears that Visual Studio projects don't support the "Disable Specific Warnings" property. This means that despite /wd options being specified in add_compile_options/target_compile_options they'll be ignored even if they would otherwise work if provided in the "Additional Options" field.
Attached is a small project that triggers a CRT deprecation warning that should be disabled by /wd4996.
Project file should be generated like so: cmake .. -G "Visual Studio 17 2022" -T ClangCL
Warning is suppressed with standard Visual C++ compiler as expected. Behavior observed in CMake 3.29.3 and Visual Studio 2022 17.10.
