[CMake] FindQt in a Specific place?

[James Willis]

So:
set (QT_QMAKE_EXECUTABLE "${mySrc}/ExternalLibs/Qt/qt_current/bin/qmake")

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 findqt3) where to find Qt?

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.
