-If your distribution does not provide ReactPhysics3D, you will have to build (and install) it yourself prior to this step

 Use the following to generate the build files:

 Then build the project using:

+The compiled binaries should then be located in `./build/bin/` and should be ready for redistribution without any further work.

+If any of the compilation steps fail, or the binaries fail to execute, please create an issue so that this can be corrected.
