CMake Configuration

All Options

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

Physics

Options / Flags	Description
-DUSE_IPHYS_PHYSICS=1	Use the open source Physics rebuild.
-DUSE_BULLET_PHYSICS=1	Use Open Source Bullet3 Physics Engine(zlib)
-DUSE_BULLET_PHYSICS_THREADED=1	Use Multi-Threading for the Bullet Physics Engine. Use convar 'bt_threadcount' to set.

No Physics Options will use the original Closed-Source vphysics.

UI

Options / Flags	Description
-DUSE_ROCKETUI=1	Use Custom RocketUI. Without this, the UI will be a broken mess of VGUI.

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

Audio

Options / Flags	Description
-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.

No Audio Options will use Open Source Audio System.

Other

• -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.

Building

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