+The Launch Bar Launch Configuration Build Settings tab has been updated so it can now correctly control the CMake Generator setting. The "Additional CMake arguments" field can also be used to inject CMake defines into the CMakeCache.txt file to populate it with customizable settings for the project. Use the new "Use these settings" checkbox to control whether to use either the operating system defaults or settings from the UI.

+When "Use these settings" checkbox is unchecked, the operating system defaults are used during the CMake build.
