You are right that it should re-run cmake automatically, and seems not to, even though it seems to reparse the project (probably based on the old data).
Either “Run CMake” or just building (since CMake will automatically run itself) will result in Qt Creator getting the update of changed CMake files. It really does what the title suggests - it runs CMake in your build directory. “Apply Configuration Changes” is only available if you changed the configuration values in that screen, and runs CMake with the corresponding -DVAR=VALUE or -UVAR arguments. So it basically includes “Run CMake”. Note that because of how _CMake_ works, a single run of CMake might not be enough to actually apply these completely, you might need to run cmake again (or CMake does it automatically when building, hopefully). “Rescan project” is just a “something went wrong, try to get the data from CMake again (without actually running CMake)”. That should probably move to a less prominent place. Do not “Clear” the CMake configuration, or be prepared to loose all configuration changes that you made in Projects mode, re-running CMake with the “Initial CMake Arguments” and completely rebuild your project.
