CMakeLists.txt

# Tells CMake how to build the project. Split into the following sections:
#   config: Sets variables and paths needed for the build. Might need to change some values to match your system.
#   flags: Set flags for compiler, linker etc.
#   dependencies: Finds packages required for the project.
#   resources: Manages the shaders and their compilation/inclusion in the output directory.
#   output: Including the source, headers and defining the output targets of the project.
