From Brad Smith:
```
I noticed odamex is currently failing to build on PowerPC with the AltiVec
support. Since we disable AltiVec support on PowerPC anyway then go ahead and
do so here as well.
```
- Use CFLAGS and CXXFLAGS instead of CMAKE_CXX_FLAGS and CMAKE_C_FLAGS.
- Use MODCMAKE_LDFLAGS instead of CMAKE_EXE_LINKER_FLAGS
- Fix broken builds with CMake 3.23
From the release notes:
"This is a small release containing a fix for an exploit that allowed players
to spy on players they weren't supposed to. It is highly recommended that all
servers update to this new release as soon as possible."
this software wants some features not on earlier cpus. (if someone has
a computer too old for this, i would give you a nickel for another
computer, but i bet you have several newer ones already..)
```
Odamex is a free, cross-platform modification of the Doom engine that allows
players to easily join servers dedicated to playing Doom online.
```
OK solene@, thanks!
