CMake provides "hack" for cmake-gui, that allows set options variants and select then from drop down list. Allows Qt Creator re-use this solution. See: - https://blog.kitware.com/constraining-values-with-comboboxes-in-cmake-cmake-gui/ - http://blog.bethcodes.com/cmake-tips-tricks-drop-down-list Drop down values can be added to option via: SET_PROPERTY(CACHE OptionName PROPERTY STRINGS Option1 Option2 Option3) This solution should not restrict to provide any other value, it provides only suggestion for user to select one of prdefined values.
