The current change allows the cmake-gui (like
ccmake
) to offer the user a fixed enumeration of possible values, so that the user can select one from a drop-down menu. In case ofccmake
the possible values are toggled by pressing enter and it is not anymore possible for the user to enter text as value.I have very basic knowledge about cmake, so there might be a different way to achieve the same result. If a different way is preferred, please go forward with it, without asking me to adopt it.
