Ok right I missed that.

Yes it does for a part of it,
now I have an apidoc target which is run "not everytime" and that's fine
and thank you for this.

The remaining part of the problem is the 'install' part of it.
Since CMake INSTALL command are processed during CMake run time
(and not build time) but my build process generates files (doxygen
produced files).
Those files won't be installed since
CMake may well not be re-runned after the file are generated.

The CMake code used for installing files is the following:
  FILE(GLOB_RECURSE doc_files RELATIVE ${APIDOC_DIR} ${APIDOC_DIR}/*)
    FOREACH(file ${doc_files})
    GET_FILENAME_COMPONENT(file_prefix ${file} PATH)
    INSTALL(FILES ${APIDOC_DIR}/${file}
     DESTINATION doc/${file_prefix})
  ENDFOREACH(file)

So the remaining question is:

How to properly INSTALL files which are generated during build time
BUT without knowing IN ADVANCE the name of the files you want to install.
In the doxygen generated files case, I don't know the exact names of the
list (may be huge) of files that will be generated.
