Qt4 will not compile with CMake

Now I'm on Linux with KDevelop for C ++, and I want to compile a Qt4 application, but when I do this, it causes the following error:

I am compiling with:

cmake -DCMAKE_INSTALL_PREFIX=/usr/local -DCMAKE_BUILD_TYPE=Debug /home/myname/projects/First Qt projet/

These are the errors:

 -- Configuring incomplete, errors occurred! CMake Error at /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:97 (MESSAGE): Could NOT find Qt4 (missing: QT_QMAKE_EXECUTABLE QT_MOC_EXECUTABLE QT_RCC_EXECUTABLE QT_UIC_EXECUTABLE QT_INCLUDE_DIR QT_LIBRARY_DIR QT_QTCORE_LIBRARY) Call Stack (most recent call first): /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:288 (_FPHSA_FAILURE_MESSAGE) /usr/share/cmake-2.8/Modules/FindQt4.cmake:1200 (FIND_PACKAGE_HANDLE_STANDARD_ARGS) CMakeLists.txt:3 (find_package)

What should I do?

 sudo apt-get install libqt4-core libqt4-dev libqt4-gui qt4-dev-tools

This should install qt4 for you at: / usr / lib64 / qt ... from there, cmake should be able to find the qt location for you.

You can also use this Ubuntu package manager if the command line is not your style.

Not sure if this helps anyone, but for Fedora I had the following problem:

CMake error in / usr / share / cmake / Modules / FindQt 4.cmake: 1386 (message): Found the wrong version of Qt "" from NOTFOUND, this code requires Qt 4.x Call stack (last call first): bgrive / CMakeLists .txt: 3 (find_package)

After going through FindQt4.cmake, I found this:

 if (NOT QT_VERSION_MAJOR EQUAL 4) set(VERSION_MSG "Found unsuitable Qt version \"${QTVERSION}\" from ${QT_QMAKE_EXECUTABLE}") set(QT4_FOUND FALSE) if(Qt4_FIND_REQUIRED) message( FATAL_ERROR "${VERSION_MSG}, this code requires Qt 4.x") else() if(NOT Qt4_FIND_QUIETLY) message( STATUS "${VERSION_MSG}") endif() endif() else() FIND_PACKAGE_HANDLE_STANDARD_ARGS(Qt4 FOUND_VAR Qt4_FOUND REQUIRED_VARS ${_QT4_FOUND_REQUIRED_VARS} VERSION_VAR QTVERSION ) endif()

I know that my qt 4I solved this by simply doing:

 sudo yum install qt-devel
