Problems building on Ubuntu

[jongeorge1999]

Followed instructions in BUILD.md, can't seem to build it due to openxr.

Yeah, I had the same problem. It kinda "fixed" by adding -DCMAKE_MAKE_PROGRAM=/usr/bin/make when executing. You also have to install libxcb-glx.
After that, I got an error where vcpkg/buildtrees/libxcrypt/config-x64-linux-dbg-config.log was not found.

@jongeorge1999 and @Bertani545 could you check my most recent PR and let me know if the build issue has been fixed?
