I fully understand the difference, thanks for worrying. If you have some problems with Nepomuk, I suggest not building it in kdelibs. but hey, wait... it's not optional in kdelibs if you have Soprano Installed (and Soprano *is* optional in kdelibs). I let you figure out how to really disable Nepomuk. I'll change find_package to macro_optional_find_package to make you happy. > Second It still doesn't compile because akonadiconsole these days has a ui > file referencing some Nepomuk Widget. > > Which leads me to the main point of this mail.

We really hope it will be a hard dependency before 4.4. There's already a thread on k.c.d about this subject. Christophe.
