Compilation difficulties in linux

[patatahooligan]

There are some nontrivial issues that I faced while compiling for linux. There should be some documentation in the readme concerning the following issues :

• System-wide dependecies : OAL, Vorbis, OGG libraries
• Local dependencies (see issue Has anyone managed to compile this? #5)
• Tools compilation

Also, other issues are :

• Compiler flag -fpermissive (?) (presumably due to the code being compiled on older gcc version)
• OALWrapper could be a git sub-project (reflect that in CMakeLists.txt)

About the tool compilation part, I managed to run HplHelper tool using monodevelop to build using the .csproj file. However, monodevelop was unable to automatically create the bin/debug/ directory to output the .exe so it had to be manually created. Also, the executable was unable to find the resources.cfg and could only be executed by creating a soft link of the executable in assets/ directory. That seemed to be enough for the .exe to run.
