[CMake] copying the contents of a directory with cpack

[Olivier Delannoy]

How could I define a custom target of name install_doxygen which is
going to use INSTALL ? I haven't seen any way to do partial
installation so far. I am missing something ?

I have a doxygen target and I would like to be able to add the output
of doxygen to the install target. But I don't want to create the
doxygen documentation each time I execute the install target.  So I am
wondering how I could create a set of file that is installed only if
previously generated.

I hope you will understand what I mean
