Additional context
It appears gmp is trying to install its header (include) files in <vcpkg-root>\installed\x64-windows\include\include -- which fails because I also have the LLGL port installed and it also has installed its header (include) files into <vcpkg-root>\installed\x64-windows\include\include\LLGL (a separate issue I will submit under a separate issue.

Both are incorrect, I believe the gmp port files should just be in the <vcpkg-root>\install\x64-windows\include and LLGL port should be in <vcpkg-port>\installed\x64-windows\include\LLGL.

In other words there is one too many include in the file destination paths.
