Since 4.8.0 is out, I\'ve reinstalled Qt, and now I want to use cmake too. To make cmake work, I remember having to add the mingw bin folder (QtSDK\\Desktop\\Qt\\4.7.3
Just ran into the same problem... Take a look into findQt4.cmake
FIND_PROGRAM(QT_QMAKE_EXECUTABLE NAMES qmake qmake4 qmake-qt4 qmake-mac PATHS
"[HKEY_CURRENT_USER\\Software\\Trolltech\\Qt3Versions\\4.0.0;InstallDir]/bin"
"[HKEY_CURRENT_USER\\Software\\Trolltech\\Versions\\4.0.0;InstallDir]/bin"
"[HKEY_CURRENT_USER\\Software\\Trolltech\\Versions\\${qt_install_version};InstallDir]/bin"
$ENV{QTDIR}/bin
DOC "The qmake executable for the Qt installation to use")
You can either alter registry keys, or, I personally prefer deleting all those keys altogether and modify $ENV{QTDIR} variable. Good luck.
