[mathgl] URL Encode

[BillyONeal]

Workaround on Ubuntu 22.04:

error: https://sourceforge.net/projects/mathgl/files/mathgl/mathgl 8.0/mathgl-8.0.1.tar.gz/download: curl failed to download with exit code 3
curl: (3) URL using bad/illegal format or missing URL

Will there be an issue to track a fix to this without workaround? Arguments should be literal, not URL-encoded.

I didn't dig into the issue enough to determine who messed up here. Given that it occurred due to Ubuntu 22.04 I'm inclined to blame curl rather than us but not sure.

I didn't want to blame anybody, and I understand that there is a tight time frame for the current update.
I just want to point out that in my opinion vcpkg cmake functions shouldn't required regular parameter values to be urlencoded. No matter if the backend is curl or whatever.
