Instead of trying to find specific build file in doc directory, I think it would be better looking and make sense if we move build-*.md files in doc to its specific new directory: doc/build/.
We can also consider renaming build-*.md files to, e.g. windows.md, and whole path can look like that : doc/build/windows.md. (Optional)
How it's going to look:
doc/build-windows.md to doc/build/build-windows.md or doc/build/windows.md
