I discovered that while porting it to a Pi ARM platform years ago (yes it was slow... lol.) Forgot when the IP becomes public domain, but you might want to check that out. If I recall it was unrelated to the COLMAP project design. =3

Personally, I recommend COLMAP + CloudCompare + MeshLab, but the Mozilla Public License 2.0 should address IP license issues if the author is also the rights holder. Keep in mind all work done by University Students and Staff is often property of the institution unless otherwise stated. It is a delicate subject.
Best of luck =3
