- Add "EXPORT paradiseo-targets" to cmake's "install" commands.
- Export those targets in "paradiseo-config.cmake",
which is needed by FindParadiseo.cmake script.
- Bugfix "FindParadiseo.cmake" script:
- document PARADISEO_ROOT input,
- add PARADISEO_DIR to specify a bin dir (try build, debug and release as defaults),
- bugfix bad copy pastes involving edo and peo,
- default messages only for eo, mo and meo.
- Fix the doc target management: now working whatever the combination of modules that is asked.
- Add edo to the doc targets.
- Add a warning when doxygen is not found.

Note that tests are still built in <build>/module/test/.
