Compilation error of the SDK on Windows using clang-cl and vcpkg

[abique]

See the vcpkg related issue:
microsoft/vcpkg#38418

In short, the vcpkg maintainers thinks the vulkan sdk is doing something wrong, see this comment: microsoft/vcpkg#38418 (comment)

The issue was also reported here as well: https://vulkan.lunarg.com/issue/view/662a58cd5df11251c5c72468

Going to copy what looks to be the 'problem' in VVL:

Looks like upstream tries to always install PDBs and clang-cl is not generating them.

Specifically, validation has the following install code

if (MSVC)
    install(FILES $<TARGET_PDB_FILE:vvl> DESTINATION ${LAYER_INSTALL_DIR})
endif()

Which appears to break when compiling with clang-cl because it doesn't generate pdb's. Why doesn't it? I don't know. I would have thought it did, maybe a compile flag to force pdb output is needed during a Release build.

How about adding -g?

if(${CMAKE_CXX_COMPILER_ID} MATCHES "Clang")
    add_compile_options(
        -Wconversion
        -Wimplicit-fallthrough
        -Wstring-conversion
        -g -gcodeview
    )
endif()
