I am trying to stop cmake from continuing generation if it outputs a warning, i.e. treat all warnings as errors and stop.
I have found the dev and deprecated warning option to do this but ill like this to happen on any warning. e.g. i have sometimes unused variables/options which outputs a cmake warning, to prevent anyone from passing unused variables to the generation i like to enable such an option.
Anyone know how to do this?
I am looking for a more general option, something like: CMAKE_WARN_AS_ERROR. the deprecated error/warning only stops on that type. Sometimes you pass an unused variable to cmake and that would output a warning which i like to prevent. if you do:
cmake -DMY_UNUSED_VAR=true
it will output
“CMake Warning: Manually-specified variables were not used by the project: MY_UNUSED_VAR”
I would like to make that warning an error, any any other CMake Warning.

I have exactly the same needs as @chrilleman . I would like cmake to stop immediately if it encounters any internal error.
This is to prevent erroneous user parameter settings. Our current project has ~20 sub-directires and we have to manage ~40 custom options. Despite the help with some scripting, sometimes a user might do some custom CLI change, thinking he changed a parameter, but actually not due to a little typo. This has happened for more than 3 time for our team. It would be very helpful if I can set the CMakeLists.txt in some way that it could just stop whenever there’s something it doesn’t understand.
