A cmake option only has two values: ON or OFF. There is no unset. Because it is a boolean. See: https://cmake.org/cmake/help/latest/command/option.html https:/

Right, but the boolean is set by an autoconf script, is it not?

This is not actually true, you can check if variables have been defined in CMake.
