update shaderc

[doomtr666]

New version supports NVidia Turing extensions (ray tracing). Tested on VS2019 Comunity.
Note that I was unable to activate SPVC options correctly (enables shader reflection and depends of spirv-cross), I had various link errors.

if glslang install/exports configs & targets this line should not be commented!

[doomtr666]

Ok, problem was with the old cmake targets patch not being applied.

I can't access Vcpkg-PR-Eager... Looking vcpkg-Linux-PR, it seems this warning causes the build to failed:
CMake Warning:
Manually-specified variables were not used by the project:

VCPKG_PLATFORM_TOOLSET

Don't know how to get rid of that ?

Hi @doomtr666, thanks for your PR. I see that spirv-tools failed on x64-Linux from the current CI system.

Hi, It seems it's this warning (analyzing step) that cause the build to fail: CMake Warning: Manually-specified variables were not used by the project: VCPKG_PLATFORM_TOOLSET But I don't know how to get rid of that ?

I found this problem during install on Linux, a requires Python module is not installed in the CI machines.

Would installing python3-distutils via apt-get on the CI machines do the trick? If so we can take care of that and rerun the tests.

[vicroms]

I haven't had time to check locally, I'll test and let you know.

[doomtr666]

Any news about the CI update ?

[dan-shaw]

I've commented out the distutils line in spirv-tools in a patch, which might fix the problem on the CI. The build seems to work, but I'm not sure if this will break anything else. So feel free to remove my changes.

[doomtr666]

I've done some tests, all is ok for me.

[dan-shaw]

Thanks for the PR!
