cmake not finding Qt4

Question

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

Answer 1

You just need to set the path to qmake in QT_QMAKE_EXECUTABLE, and then cmake can use qmake -query to find all the other paths it needs (similar to pkg-config on Linux).

Steps for building a project using Qt and CMake usually are:

1. Check out / create project source folder
2. Create build folder outside the project folder
3. Start Qt command prompt / cmd and cd into build folder e.g. cd build\project
4. Run cmake or cmake-gui passing path to source folder e.g. cmake-gui ..\..\source\project
5. Set any variables, such as QT_QMAKE_EXECUTABLE and CMAKE_BUILD_TYPE
6. Run your build tool, or run cmake --build .
