The spaces may be in parent folders, such as c:\Users\Jean-Michaël Celerier\Documents\Visual Studio Projects\Project 1\...

Which your uni's group policy would make it so that you can only write there (thankfully mine was sane, but I've seen it aha).

And even then, a build system that does not support arbitrary file names is just terminally broken and should not be used, even less encouraged.

That's "only" a problem for absolute paths, most projects which use makefiles use relative paths.

Spaces are the lesser evil. Try newlines in file names. Also try having a directory that contains ":" in PATH.
