Qt4 needed for building using autotools? && Wonders.

I'm trying to build some trinity components manually, since no binaries, nor build scrips (PKGBUILD) are available for my distro (arch), and I wonder, why when I try to compile something using autotools (because obviously it hasn't been ported to cmake yet) it keeps me asking for Qt >=4.3 and <5.0. Besides I looked a little at files present in the admin dir and I found that some of the paths for libraries are hardcoded and point to (example) /usr/share/kde3 or /usr/share/qt. Another thing, shouldn't automake files be removed form components that have been ported to CMake. Since autotools-based compiling aren't really supported for those... And I'd be grateful of someone could write a little about how to port trinity components to cmake. I'd like to help, I get the main idea, but I don't know where too look for dependencies and stuff like that.
