Write formulae that depends on vulkan-sdk

[CarterLi]

More multi-platform libs have vulkan support, for example libplacebo. We do have molten-vk however most libraries requires full vulkan sdk

Any suggestions?

Is the sdk open source?
Yes -> make it into a formula and declare it as dependency

No ->
Is your formula in a non-homebrew tap?
Yes -> you can depend on whatever you want

No -> non-formula dependencies are not allowed in homebrew, but you can always ship it in a personal tap.

How can I make my tap find the sdk? The library uses pkg-config and vulkan sdk .pc files were installed in /usr/local/lib/pkgconfig/

From https://people.freedesktop.org/~dbn/pkg-config-guide.html:

The message above references the PKG_CONFIG_PATH environment variable. This variable is used to augment pkg-config's search path.

Well, no. Homebrew seems rewriting PKG_CONFIG_PATH. I can build the lib manually with vulkan support, but not with homebrew formula
