CMake

How to build

You will want to do your builds in the cmake-build folder.

Specify various options with the -D flag (example below)

cmake .. -DOPTION1=0 -DOPTION2=1

CMake Configuration

All Options

See this file for up-to-date options choices - (in case the wiki is not updated).

Physics

• -DUSE_KISAK_PHYSICS=1
  • Use the open source Physics rebuild.
• -DUSE_BULLET_PHYSICS=1
  • Use the open source and free-as-in-freedom Bullet Physics Library.
  • -DUSE_BULLET_PHYSICS_THREADED=1
    • (For Bullet Physics) - Use experimental threading option. Use convar bt_threadcount to control the amount of threads.

No Physics Options will use a Closed-Source Binary from Valve (734 repo)

UI

• -DUSE_ROCKETUI=1
  • Use Custom RocketUI. Without this, the UI will be a broken mess of VGUI. (Scaleform is disabled by default use -DUSE_SCALEFORM=1 if you really want)
• -DDEDICATED=1
  • Change the build to dedicated server mode. Note that the builds are not in-tree compatible, some things will have to be rebuilt. Make sure to use -DDEDICATED=0 once you want to go back to the client build.

No UI Options will leave the game's built-in VGUI UI. Note that it is unfinished and broken!

Audio

• -DUSE_VALVE_HRTF=1
  • By default the HRTF is disabled because it requires a proprietary blob(libphonon3d.so), set this flag to re-enable it.

Building

After cmake, simply do a make -jXXX where XXX is the number of threads you wish to build with.
