Compiling release version of RoR (Linux) without conan

First install nvidia-cg-toolkit

then we need to get dependencies compiled

git clone https://github.com/RigsOfRods/ror-dependencies
cd ror-dependencies
cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo .
make -j8

Αfter that we need to clone ror it self

git clone --recursive https://github.com/RigsOfRods/rigs-of-rods
cd rigs-of-rods
cmake -DCMAKE_PREFIX_PATH=~/ror-dependencies/Dependencies_Linux/ -DCMAKE_BUILD_TYPE=RelWithDebInfo -DUSE_PACKAGE_MANAGER=OFF .
make -j8

and thats it!
