external_deps: failing to build GLEW for MSVC

I get those two errors when trying to build GLEW for the MSVC packages:

I first got it with on my deps update branch:

• https://github.com/DaemonEngine/Daemon/pull/857

But I reproduce the issue on current master.

This was reproduced on Debian Buster.

This should be fixed, I merged a lot of fixes and I don't reproduce it on my "update deps" branch rebased on those fixes.
