The FindQt4 module of CMake insists on having uic, even if the QtGui
module isn't part of the requirements to build the program. This isn't
correct, as Qt doesn't build/install the uic program when QtGui is
disabled (uic is used to generate some UI code).
This has been fixed upstream in
http://cmake.org/gitweb?p=cmake.git;a=commit;h=43cb9b8276a70d153d56a69d5c61daaf2bc51b78. This
commit will be part of the upcoming 2.8.4 CMake release, but in the
mean time, let's include it in Buildroot.
From 43cb9b8276a70d153d56a69d5c61daaf2bc51b78 Mon Sep 17 00:00:00 2001
From: Clinton Stimpson <clinton@elemtech.com>
Date: Fri, 14 Jan 2011 21:26:19 -0700
Subject: [PATCH] Change to use fphsa to check required variables and version.
Also, set the required variables based on components, if specified.
Also, don't make finding uic required if not using QtGui.
