Create a normal configuration file for doxygen replace some of it by  
variables and use configure_file().
Some that are good candidates:
PROJECT_NUMBER
   You may want to keep version numbers in one place (in CmakeLists.txt)

OUTPUT_DIRECTORY
INPUT
   As those may change when doing out-of-source builds, this is rather  
mandatory.

GENERATE_*
   You can generate more that one Doxyfile from a Doxyfile.in, each used to
   generate another output format. Connect that to custom commands and targets.

Most of the other stuff is probably static enough to leave them fixed  
in the template .in file.
