For SDL 2 replace "libSDL-devel" with "libSDL2-devel".
"libffmpeg1-devel" requires the PackMan repository. If you don't have that repo, and don't want to add it, remove the "libffmpeg1-devel" option and compile without ffmpeg support.
If you have the repo and compiles with ffmpeg support, make sure you download "libffmpeg1-devel", and not "libffmpeg-devel".

Instead of SDL1.2 development files you can also use SDL2, but so far it
seems like no distributions except openSUSE has packages for it yet, so you may have to
compile and install SDL2 yourself.
(There may be inofficial repositories like Ubuntu PPAs)
Instead of SDL1.2 development files you can also use SDL2. Install SDL 2.0 and add to the cmake parameters -DSDL2=ON
SDL2 has better input support (especially in the console) and better
support for multiple displays (especially in fullscreen mode).

If you use the prebuilt Win32 binaries then simply extract them to your
C:\Program Files (x86)\Steam\SteamApps\common\Doom 3 BFG Edition\ directory and run RBDoom3BFG.exe.
The following instructions are primarily intented for Linux users and all hackers on other operating systems.
To play the game, you need the game data from a legal copy of the game, which
unfortunately requires Steam for Windows - Steam for Linux or OSX won't do, because
(at least currently) the Doom 3 BFG game is only installable on Steam for Windows.

- Flexible build system using CMake
- Linux support (32 and 64 bit)
- New OpenAL Soft sound backend primarily developed for Linux but works on Windows as well
- Win64 support
- Implemented soft shadows using PCF hardware shadow mapping
The implementation uses sampler2DArrayShadow and PCF which usually
requires Direct3D 10.1 however it is in the OpenGL 3.2 core so it should
be widely supported.
All 3 light types are supported which means parallel lights (sun) use
scene independent cascaded shadow mapping.
The implementation is very fast with single taps (400 fps average per
scene on a GTX 660 ti OC) however I defaulted it to 16 taps so the shadows look
really good which should you give stable 100 fps on todays hardware.
The shadow filtering algorithm is based on Carmack's research which was
released in the original Doom 3 GPL release draw_exp.cpp.
- Changed light interaction shaders to use Half-Lambert lighting like in Half-Life 2 to
make the game less dark. https://developer.valvesoftware.com/wiki/Half_Lambert

// TODO
r_useShadowMapping 1 - Use soft shadow mapping instead of hard stencil shadows
___________________________________________________
10) CONSOLE VARIABLES
10) KNOWN ISSUES
__________________________________________
// TODO
Doom 3 wasn't designed to work with shadow maps so:
- Some lights cause shadow acne with shadow mapping
- Some shadows might almost disappear due to the shadow filtering

11) KNOWN ISSUES
__________________________________________
* Doomclassic is not supported on Linux (yet)
* There are some issues with the binary format loaders/writers on 64 bit platforms
* The intel open source drivers to not support OpenGL 3.2 yet
