Ona currently depends the following third-party tools to build it:
|
||||
|
||||
* Platform support for SDL2 at version 2.0.20 or above.
|
||||
* SPIR-V shader compilation system utilities, namely `glslangValidator` and `spirv-link`.
|
||||
* Zig compiler toolchain.
|
||||
|

As the project evolves, dependencies on libraries external to the project codebase will be minimized or removed outright to meet the goals of the project as closely as possible.
