Theoretically the free VC++ 2017 version from Microsoft and the dependencies listed at the ReShade Github repository (Python.) should allow for compiling the source code yourself and any wanted pull requests but yeah it's not as easy if you have no prior experience with this even if the Github page has all the information needed from it's readme.

If this commit does make it into the 3.1.1 release then the next public release should be a interesting one to test in a few formerly problematic games when it comes to depth detection.
But yeah spreading out compiled versions of ReShade can complicate things, Crosire might have some opinions on the pull request too and perhaps suggestions for changes so the merged commit might differ from the initial one as well.
Though ReShade isn't a absolute maze of pending pull requests and dependencies like some other Github projects and such, there are a few clones of it though doing things such as a utility tuned specifically for Guild Wars 2 and a few others but post 3.1.0 it's been pretty quiet from what I can see.
