[macOS] Build fail since d3d10 enabled

[flukejones]

Compiling both from the git repo as is, and using Valve Proton, the build fails when trying to change the rpath of d3d10core.dll.

Trying this manually results in:

error: /Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/install_name_tool: input file: /Users/luke/src/dxvk/test/bin/d3d10core.dll is not a Mach-O file

I cannot support Mac OS X and I have no way to test this. If you can get it to build, feel free to file a pull request.

There is this if you really want to build it on your machine: https://github.com/cheald/dxvk-docker

@doitsujin It's kind of critical to Valve's Proton if they intend to support macOS at all. I'll continue to see if I can fix it.

[doitsujin]

If they intend to support Mac OS X, someone will have to get MoltenVK into shape and figure out how to link it to dxvk. Right now it is impossible to even use it.

[flukejones]

@doitsujin I'm still exploring everything that encompasses Proton - you say DXVK is actually linking to Vulkan libs?
