Cam't build tests with meson in Linux

[JPeterMugaas]

When trying to build the tests with meson, I get a problem with d3d12 not found and the tests do NOT build. I'm sure that this is NOT a linux issue because when I build with cmake in Linux, I am able to build and run the tests. Looking at the meson scripts, I have to wonder why we are looking for "d3d12" because I thought we were supposed to create it but I might be missing something.

I'm using Archlinux with wsl2. Here's the build log from my process.

ninja: build stopped: subcommand failed.

110 will at least fix the build failures by causing the tests to be skipped. I forgot that this isn't the default behavior for a not-found library.

In WSL, these libraries are made available in /usr/lib/wsl/lib, which is added to LD_LIBRARY_PATH automatically (unless disabled), which allows the runtime linker to find them out-of-the-box, but the static linker can't find them without additional configuration. You can add that path to the LIBRARY_PATH environment variable (according to the comment at the top of this docs page) to get meson to actually find those libraries.

I tried #110 but that did not work when doing something like "ninja test".

My impression is that it's not able to locate the static libraries, libd3dx12-format-properties.a and libDirectX-Guids.a.
