If the webgui component is selected but not http, the compialtion will fail:
gmake[2]: *** Brak reguł do zrobienia obiektu 'gui/webdisplay/RHTTP', wymaganego przez 'gui/webdisplay/G__ROOTWebDisplay.cxx'. Stop.
gmake[1]: *** [CMakeFiles/Makefile2:38292: gui/webdisplay/CMakeFiles/G__ROOTWebDisplay.dir/all] Błąd 2
(sorry for wrong language) but it says that no rules to make RHTTP required by webdisplay. One needs to enable also http component to make it working. Cmake macros should probably detect that and pull http or give a feedback to the user about conflicting options, and should abort at configure step.
