For QMake-based projects, include color_widgets.pri in the QMake project file. For CMake-based projects, add this as subdirectory, it will be compiled as a library and you can link the required targets to ColorWidgets-qt5. All the required files are in ./src and ./include.

The sources for the designer plugin are in ./color_widgets_designer_plugin

Compile the library and install in (Qt SDK)/Tools/QtCreator/bin/designer/ (Qt SDK)/(Qt Version)/(Toolchain)/plugins/designer

cd color_widgets_designer_plugin && qmake && make && make install
