This is normal. As qml-box2d is not directly installed in the system as a
package, it will build it as a submodule.

Not important, it is to build the documentation.

This is the issue. For some reason, the compilation of the qml-box2d
submodule do not include the default paths.
I don't really have a clue for now, maybe check the logs to find if there
is something wrong?
