Sample Qt 5.15 (QtWidgets) CMake hello world

Sample QtWidgets application (+extras):

• C++ 17, Qt5.15, CMake, CCache
• Main and About window
• Embedded Qt resource (QRC)
• static utils class
• Config directory + config file

See also:

• Qt5 QtWidgets template (this): qt5-widgets-cmake-hello-world
• Qt5 QML template: qt5-qml-cmake-hello-world
• Qt5 Widgets + QML template: qt5-widgets-qml-cmake-hello-world

Installation (Linux / Mac OS)

To build, run:

cmake -Bbuild .
make -Cbuild -j4

And if you have Qt installed in a custom directory, use this CMake command instead:

cmake -DCMAKE_PREFIX_PATH="/home/user/qt5.15/gcc_64" -Bbuild .

Which will produce the dynamically linked executable build/bin/hello
