Library SCons boilerplate to build projects.
Works by executing project `SConstruct`s file in a cloned env (a bit like Godot does for modules) so you don't have to worry about platform and toolchain setup. Convert the project test file to work as submodule, add it to CI Run with: ``` scons build_projects=test,/path/to/other/project ```pull/636/head
