Install gcc and g++, make and cmake. On Ubuntu you would do that like so:
sudo apt-get install gcc g++ make cmake
If you're on a 64-bit system you'll need additional packages for compiling for 32-bit:
sudo apt-get install gcc-multilib g++-multilib
For CentOS:
yum install gcc gcc-c++ cmake28 make
cd SKY
mkdir build && cd build
cmake ../ -DCMAKE_BUILD_TYPE=Release
make
You'll need to install CMake and Visual Studio, once you have that then you can run the command below to build
cd SKY
mkdir build && cd build
cmake ../ -A Win32
cmake --build . --config Release
or you can open the source in Visual Studio, where it will autodetect that it uses CMake, and will build a cache ready to be built
