I'm building doxygen for use with the Fink project (macOS package manager). Our current doxygen is pretty old (1.8.9.1) so I'm working on updating our package to 1.8.14. I have the main executable all built up, but I'm failing at building the docs.

Our current package builds the docs as a separate package (./configure; make docs) using the already installed doxygen executable. This does not seem possible with doxygen-1.8.14. cmake .. ; cd doc; make docs still tries to build the doxygen executable from scratch. Is it still possible to separate the builds of the executable and the docs?
