Um, yea, you don't want to do that, change the location of the Qt
libraries after they are built in one location. On Windows, the only
way you can do that (to my knowledge) is to use the MinGW precompiled
binaries from Nokia. When the installer runs all the paths are updated
for the install location. As far as I can tell, Nokia has not released
the installer build scripts for Qt built under Visual Studio. You seem
to need a commercial license for that.
So, With Qt, Pick a location where EVERYONE can have Qt installed,
build it in THAT location, then you can move the installation from
computer to computer. Yes, it sucks.

So:

This initially worked. But only initially. Then I did something
dastardly: I got rid of the original place I compiled the libraries
-- which qmake still somehow knows despite being compiled with -no-
rpath.
Now I get this error:
Warning: QT_QMAKE_EXECUTABLE reported QT_INSTALL_LIBS as /home/
myName/qt-everywhere-commercial-src-4.6.0/Release/lib
Warning: /home/myName/qt-everywhere-commercial-src-4.6.0/Release/lib
does NOT exist, Qt must NOT be installed correctly.
CMake Error at /home/jwillis/cmake-2.8.0/Modules/FindQt4.cmake:673
(MESSAGE):
Could NOT find QtCore header
I also tried Tyler's idea, which fails in exactly the same way, with
the same error.
The idea here is my group has people who may want to compile the
code elsewhere on various different machines without installing any
libraries. We're dependent on a bunch right now, and it's a pain
for each developer to have to get the right version of the right
libraries, in the right order, to compile on their machine. So we
just stick already compiled versions in a seperate libs
directories. And no, we'd actually prefer their location set in the
cmakefile so we can change centrally when we decide to upgrade
libraries.
Thanks for the help so far, but I'm still hacking away at the moment.

I think if you set these two variables you will get the same desired
result.
set(DESIRED_QT_VERSION 4)
set(QT_QMAKE_EXECUTABLE /home/qt/4.6.0/bin/qmake)

Is there any good way of telling findqt (I don't really care about

Like say you did:
set(QT_QMAKE_LOCATION /home/myself/qt4.6.0/bin)
so that I later upgrade and do:
set(QT_QMAKE_LOCATION /home/myself/qt4.6.1/bin) later without having
to muck with my path, but still have findQt find Qt there?
I was looking at writing such a feature, if it's not there, and if
you'd be willing to take it as a patch.
