How to get a single PDF document from Doxygen?

Question

When I generate Doxygen documentation in PDF format, I get plenty of different files with a single diagram in each.
Is it possible to obtain a single PDF document, organized

Answer 1

Other people didn't mention a detail:

For the pdflatex route to work, your current working directory needs to be the generated latex folder, otherwise you get errors like doxygen.sty cannot be found.
