Doxygen page for another project.
I have a project called fseq4c and I want to publish a Doxygen page of fseq4c source code, so I fork pages/doxygen repository and renamed to fseq4c.gitlab.io. I followed steps in its README.md file but what about if source code that I want to be documented by Doxygen is in other repository.
Source code is in fseq4c repository and documentation pages is in another: fseq4c.gitlab.io.
