CMake issue:

```
CMake Error at CMakeLists.txt:1 (cmake_minimum_required):
   Compatibility with CMake < 3.5 has been removed from CMake.

   Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
   to tell CMake that the project requires at least <min> but has been updated
   to work with policies introduced by <max> or earlier.

   Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway. 
```

gmake/gmake2 issue:

```
Premake args:  --with-lto --without-pch --bindir=/usr/bin --libdir=/usr/lib/0ad --datadir=/usr/share/0ad/data
** Warning: gmake2 has been renamed to gmake. Use gmake to generate makefiles instead.
Premake action 'gmake' is no longer supported by pyrogenesis, use 'gmake2'
Example: 'premake5 --file=build/premake/premake5.lua gmake2'
ERROR: Premake failed
```

Patch (more like a bypass I guess):
