[solved]CMake cannot find QT5
I whant to build OSG with QT5.
With qt4 it works fine but with QT5 I get the following message from CMake
CMake Warning at C:/Program Files (x86)/CMake/share/cmake-3.0/Modules/FindQt4.cmake:616 (message):
c:/Qt/Qt5.3.0/5.3/msvc2013_opengl/bin/qmake.exe reported QT_INSTALL_LIBS as
"C:/Qt/Qt5.3.0/5.3/msvc2013_opengl/lib" but QtCore could not be found
there. Qt is NOT installed correctly for the target build environment.
Can you show the Qt 5 part of your CMakeList.txt ? Also, do you have e.g. Qt5CoreConfig.cmake in your installation somewhere ?
There is not Qt5CoreConfig.cmake file in my installation somewhere.
This is the part where tryed to find qt
Include macro utilities here
OPTION(OSG_USE_QT "Enable to use Qt (build Qt-dependent libraries, plugins and examples)" ON)
IF(OSG_USE_QT AND NOT ANDROID)
To select a specific version of QT define DESIRED_QT_VERSION
via cmake -DDESIRED_QT_VERSION=5
QUIET option disables messages if the package cannot be found.
IF (DESIRED_QT_VERSION) IF (DESIRED_QT_VERSION MATCHES 5) FIND_PACKAGE(Qt5Widgets) ELSEIF (DESIRED_QT_VERSION MATCHES 4) FIND_PACKAGE(Qt4) ELSE() FIND_PACKAGE(Qt3) ENDIF() ELSE() FIND_PACKAGE(Qt5Widgets QUIET) IF ( Qt5Widgets_FOUND ) # CMake 2.8.8 or greater required BUILDER_VERSION_GREATER(2 8 7) IF(NOT VALID_BUILDER_VERSION) MESSAGE( SEND_ERROR "Qt5 requires CMake version 2.8.8 or greater!\n" "Update CMake or set DESIRED_QT_VERSION to less than 5 or disable OSG_USE_QT." ) ENDIF( ) ENDIF( ) IF ( NOT Qt5Widgets_FOUND ) FIND_PACKAGE(Qt4) IF (NOT QT4_FOUND) FIND_PACKAGE(Qt3) ENDIF() ENDIF() ENDIF() #If we have found Qt5, let's try to top off by getting the webkit as well IF ( Qt5Widgets_FOUND ) FIND_PACKAGE(Qt5WebKitWidgets QUIET) ENDIF()
Do you have any cmake related file in your Qt installation ?
What do you mean exactly ?
Before I built other project with Qt4. That's all
check if C:/Qt/Qt5.3.0/5.3/msvc2013_opengl/ contains anything cmake related
I have solved the problem writing this
@set(CMAKE_PREFIX_PATH "C:\Qt\Qt5.3.0\5.3\msvc2013_opengl" CACHE PATH "")
set(CMAKE_LIBRARY_PATH "C:\Program Files (x86)\Windows Kits\8.0\Lib\win8\um\x86")
You're welcome !
Since you have it finding Qt 5 now, please update the thread title prepending [solved] so other forum users may know a solution has been found :)
