arts configure - attempting to compile Trinity without the Trinity Qt Interface installed? Warning OK?

I thought I had this sorted, but alas no... The arts ./configure is failing to find TQt and issuing the following warning: <snip> checking for Qt... libraries /opt/qt/lib, headers /opt/qt/include using -mt checking for moc... /opt/qt/bin/moc checking for uic-tqt... /usr/bin/uic-tqt checking whether uic supports -L ... yes checking whether uic supports -nounload ... yes checking if TQt is available... no configure: WARNING: You are attempting to compile Trinity without the Trinity Qt Interface installed. Please install libtqtinterface-dev and try again! The configure completes successfully, but I'm concerned about the warning. Looking at 'configure' itself, it seems to adjust for this with: if ${kde_cv_tqt+:} false; then : $as_echo_n "(cached) " >&6 else <do other stuff> So is this Warning OK? Obviously, Trinity isn't installed yet, so I suspect that is producing the warning, but I want to check to make sure there isn't something I need to fix before proceeding. cmake completes fine on arts :) -- David C.
