Hello, when inspecting the "libcaldav.pc" and "libcarddav.pc" provided by the libraries, it looks like they do not return a specific subdir for header files. That's why CMAKE doesn't find them.
So, in the Fedora/RHEL build, I've decided to move the caldav/carddav headers directly under /opt/trinity/include (no subdirectory), they are found by CMAKE.
Thanks. I found the same thing last night. The make files needed a couple of tweaks too. I submitted a patch:

Everything builds correctly with the patch. :)
