# - Searches for all installed versions of Qt. # This should only be used if your project can work with multiple # versions of Qt. If not, you should just directly use FindQt4 or FindQt3. # If multiple versions of Qt are found on the machine, then # The user must set the option DESIRED_QT_VERSION to the version # they want to use. If only one version of qt is found on the machine, # then the DESIRED_QT_VERSION is set to that version and the # matching FindQt3 or FindQt4 module is included. # Once the user sets DESIRED_QT_VERSION, then the FindQt3 or FindQt4 module # is included. # # QT_REQUIRED if this is set to TRUE then if CMake can # not find Qt4 or Qt3 an error is raised # and a message is sent to the user. # # DESIRED_QT_VERSION OPTION is created # QT4_INSTALLED is set to TRUE if qt4 is found. # QT3_INSTALLED is set to TRUE if qt3 is found. #============================================================================= # Copyright 2001-2009 Kitware, Inc. # # Distributed under the OSI-approved BSD License (the "License"); # see accompanying file Copyright.txt for details. # # This software is distributed WITHOUT ANY WARRANTY; without even the # implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. # See the License for more information. #============================================================================= # (To distribute this file outside of CMake, substitute the full # License text for the above reference.) # look for signs of qt3 installations file(GLOB GLOB_TEMP_VAR /usr/lib/qt-3*/bin/qmake) if(GLOB_TEMP_VAR) set(QT3_INSTALLED TRUE) endif() set(GLOB_TEMP_VAR) file(GLOB GLOB_TEMP_VAR /usr/local/qt-x11-commercial-3*/bin/qmake) if(GLOB_TEMP_VAR) set(QT3_INSTALLED TRUE) endif() set(GLOB_TEMP_VAR) # look for qt4 installations file(GLOB GLOB_TEMP_VAR /usr/local/qt-x11-commercial-4*/bin/qmake) if(GLOB_TEMP_VAR) set(QT4_INSTALLED TRUE) endif() set(GLOB_TEMP_VAR) file(GLOB GLOB_TEMP_VAR /usr/local/Trolltech/Qt-4*/bin/qmake) if(GLOB_TEMP_VAR) set(QT4_INSTALLED TRUE) endif() set(GLOB_TEMP_VAR) # now find qmake find_program(QT_QMAKE_EXECUTABLE_FINDQT NAMES qmake PATHS "${QT_SEARCH_PATH}/bin" "$ENV{QTDIR}/bin") if(QT_QMAKE_EXECUTABLE_FINDQT) exec_program(${QT_QMAKE_EXECUTABLE_FINDQT} ARGS "-query QT_VERSION" OUTPUT_VARIABLE QTVERSION) if(QTVERSION MATCHES "4.*") set(QT_QMAKE_EXECUTABLE ${QT_QMAKE_EXECUTABLE_FINDQT} CACHE PATH "Qt4 qmake program.") set(QT4_INSTALLED TRUE) endif() if(QTVERSION MATCHES "Unknown") set(QT3_INSTALLED TRUE) endif() endif() if(QT_QMAKE_EXECUTABLE_FINDQT) exec_program( ${QT_QMAKE_EXECUTABLE_FINDQT} ARGS "-query QT_INSTALL_HEADERS" OUTPUT_VARIABLE qt_headers ) endif() find_file( QT4_QGLOBAL_H_FILE qglobal.h "${QT_SEARCH_PATH}/Qt/include" "[HKEY_CURRENT_USER\\Software\\Trolltech\\Qt3Versions\\4.0.0;InstallDir]/include/Qt" "[HKEY_CURRENT_USER\\Software\\Trolltech\\Versions\\4.0.0;InstallDir]/include/Qt" ${qt_headers}/Qt $ENV{QTDIR}/include/Qt /usr/local/qt/include/Qt /usr/local/include/Qt /usr/lib/qt/include/Qt /usr/include/Qt /usr/share/qt4/include/Qt C:/Progra~1/qt/include/Qt ) if(QT4_QGLOBAL_H_FILE) set(QT4_INSTALLED TRUE) endif() find_file( QT3_QGLOBAL_H_FILE qglobal.h "${QT_SEARCH_PATH}/Qt/include" "[HKEY_CURRENT_USER\\Software\\Trolltech\\Qt3Versions\\3.2.1;InstallDir]/include/Qt" "[HKEY_CURRENT_USER\\Software\\Trolltech\\Qt3Versions\\3.2.0;InstallDir]/include/Qt" "[HKEY_CURRENT_USER\\Software\\Trolltech\\Qt3Versions\\3.1.0;InstallDir]/include/Qt" C:/Qt/3.3.3Educational/include $ENV{QTDIR}/include /usr/include/qt3/Qt /usr/local/qt/include /usr/local/include /usr/lib/qt/include /usr/include /usr/share/qt3/include C:/Progra~1/qt/include /usr/include/qt3 ) if(QT3_QGLOBAL_H_FILE) set(QT3_INSTALLED TRUE) endif() if(QT3_INSTALLED AND QT4_INSTALLED ) # force user to pick if we have both set(DESIRED_QT_VERSION 0 CACHE STRING "Pick a version of Qt to use: 3 or 4") else() # if only one found then pick that one if(QT3_INSTALLED) set(DESIRED_QT_VERSION 3 CACHE STRING "Pick a version of Qt to use: 3 or 4") endif() if(QT4_INSTALLED) set(DESIRED_QT_VERSION 4 CACHE STRING "Pick a version of Qt to use: 3 or 4") endif() endif() if(DESIRED_QT_VERSION MATCHES 3) set(Qt3_FIND_REQUIRED ${Qt_FIND_REQUIRED}) set(Qt3_FIND_QUIETLY ${Qt_FIND_QUIETLY}) include(FindQt3) endif() if(DESIRED_QT_VERSION MATCHES 4) set(Qt4_FIND_REQUIRED ${Qt_FIND_REQUIRED}) set(Qt4_FIND_QUIETLY ${Qt_FIND_QUIETLY}) include(FindQt4) endif() if(NOT QT3_INSTALLED AND NOT QT4_INSTALLED) if(QT_REQUIRED) message(SEND_ERROR "CMake was unable to find any Qt versions, put qmake in your path, or set QT_QMAKE_EXECUTABLE.") endif() else() if(NOT QT_FOUND AND NOT DESIRED_QT_VERSION) if(QT_REQUIRED) message(SEND_ERROR "Multiple versions of Qt found please set DESIRED_QT_VERSION") else() message("Multiple versions of Qt found please set DESIRED_QT_VERSION") endif() endif() if(NOT QT_FOUND AND DESIRED_QT_VERSION) if(QT_REQUIRED) message(FATAL_ERROR "CMake was unable to find Qt version: ${DESIRED_QT_VERSION}.
