If "qt_build" provides a separate development package or SDK, be sure it has been installed. Under Linux, the cmake-data package installs a list of Qt files that help you with finding the Qt library, compiling with the Qt library, linking against the Qt library. cmake:1200 (FIND_PACKAGE_HANDLE_STANDARD_ARGS) Problem while running initial CMake It seems it is looking for QT, but that too has been installed CMake is used to control the software compilation process using simple platform and compiler independent configuration files. You can set the the Qt dir when configuring via CMake: `-DQt5_DIR="<Path to Qt dir>" On Windows the path you need is something like this: <Qt Dir>/<version>/<build type>/lib/cmake/Qt5. Hopefully this should be enough to get you started. Could not find a package configuration file provided by "Qt5Core" (requested version 5. I read the introduction of cmake in the book Foundations Of Qt Development. So let's say you have a project that depends on Qt5 and you need to copy the relevant dlls to your build directory and you don't want to do it manually; you can do the following: Once you modify the environment variables, you need to restart CMake and click “Configure” again.

CMake - the cross-platform, open-source build system. CMake is a cross-platform tool; the idea is to have a single definition of how the project is built - which translates into specific build definitions for any supported platform. We also see that QtCreator doesn’t pass a toolchain file to CMake. . Test Example The cloned one should appear in the list of manually defined kits. Some less obvious build configuration points-of-care are highlighted. set (CMAKE_INCLUDE_CURRENT_DIR ON) # Tell CMake to run moc when needed.
