[Linux] Penumbra: Black Plague crashing at startup due to OpenAL sound function error

Hello, I'm running the game through a Linux VM and I'm getting a crash when launching it. We figured out the problem is in the function here : https://github.com/FrictionalGames/OALWrapper/blob/master/sources/OAL_Device.cpp#L77

Here is the gdb infos while launching the game :

Parse error.  Expected a command name, got unquoted argument with text "${CMAKE_CURRENT_SOURCE_DIR}/sources/*.cpp".
-- Configuring incomplete, errors occurred!

There's a ')' missing at the end of line 13 in CMakeLists.txt

OV_CALLBACKS_DEFAULT : undeclared identifier. in the OAL_OggStream.cpp file

OV_CALLBACKS_DEFAULT' : undeclared identifier on line 148 and line 157, the definiton or the declaration is no nowhere to be found

Please add more checks in CMakeLists.txt for Linux

the following libs needs to be checked for by cmake :

freealut, sdl, openal, vorbis

Also, it would be cooler to create a shared library instead of a static one, or at least give an option for that
