Thats what Clinton did, so how about trying exactly what he wrote?
Ok, removing the two message() lines (which is exactly what Clinton
wrote) produces:
-- Found Qt-Version 4.3.5
-- Configuring done
-- Generating done
-- Build files have been written to: /ldisk/localstorage/proj/cmake/qt_test
I don't see how that helps, since I can't tell what library and
include paths are being detected.
In particular you could try without the QT_USE_FILE and see wether the
variables are different then.
Ok, this:
find_package(Qt4)
message(${QT_LIBRARY_DIR}) # prints "/usr/lib"
message(${QT_INCLUDE_DIR}) # prints "/usr/lib/qt3/include"
produces this output:
-- Found Qt-Version 4.3.5
/usr/lib
/usr/lib/qt3/include
-- Configuring done
-- Generating done
-- Build files have been written to: /ldisk/localstorage/proj/cmake/qt_test
If not the next step would be to start
putting message() calls into FindQt4.cmake in CMake's Modules/ directory to
find out why it uses the wrong qmake or wether maybe the qmake supplies the
wrong paths.
The explicit path to qmake I was using in the original CMakeLists.txt
in my original post was /usr/local/Trolltech/Qt-4.3.5/bin/qmake.
This:
/usr/local/Trolltech/Qt-4.3.5/bin/qmake -v
yields this:
QMake version 2.01a
Using Qt version 4.3.5 in /usr/local/Trolltech/Qt-4.3.5/lib
Another data point -- there was one qmake in my path for all the runs
above, and in all the runs in my previous posts,
/usr/lib/qt3/bin/qmake. When I removed this qmake, nothing changed.
In fact, now 'which qmake' reports there is no qmake in my path, and
yet FindQt4 still sets the Qt include path to /usr/lib/qt3/include.
As for debugging FindQt4.cmake, surely I'm not the only person ever to
try to use FindQt4 with qt3-devel and qt4-devel, plus another
user-installed Qt version. If it's finding the wrong qmake, it's
surely my fault for using it wrong, not the FindQt4.cmake file. I'm
just trying to figure out the script-fu necessary to get it to play
nicely.
Does anyone know what the magic incantation is?
I have Qt3 and Qt4 on my machine too, and I don't have this kind of problem.
Maybe this'll help narrow down the problem.
Can you try this (unmodified), and with a clean build directory (I want
to see it checking the C and C++ compiler too)?
=== CMakeLists.txt ===
find_package(Qt4)
message("qmake exec = ${QT_QMAKE_EXECUTABLE}")
message("qt inc = ${QT_INCLUDE_DIR}")
message("qt core inc = ${QT_QTCORE_INCLUDE_DIR}")
message("qt headers dir = ${QT_HEADERS_DIR}")
exec_program( ${QT_QMAKE_EXECUTABLE}
ARGS "-query QT_INSTALL_HEADERS"
OUTPUT_VARIABLE qt_header_dir )
message("qt header dir 2 = ${qt_header_dir}")
