Building from Source
Checkout the repository
git clone https://github.com/egoboo/egoboo
into some directory called the source directory.
Change into the source directory and initialize and update the submodules
git submodule update --init --recursive
Next, perform an out of source build by creating a directory called the build directory. The build directory must reside outside of the source directory. Change into the buid directory and enter
cmake <path to source directory>
where <path to source directory> is replaced by the actual path to your source directory.
CMake will generate the environment specific build files (e.g., Visual Studio files, Make files, etc.) in the build directory.
