Tips for adding and removing Gems

  • When you register a new Gem to your project, the path to the Gem’s directory is added in your project’s project.json configuration file under external_subdirectories.

  • To check if a Gem is enabled for your project, you can find the list of enabled Gems in your project folder in the Code/enabled_gems.cmake file.

CMake error: Not an existing directory

Issue: CMake cannot find the directory of the specified Gem. When adding external Gems to your project, you must register the Gem’s directory to your project. This enables your project to find the Gem. This issue may occur if the Gem’s directory location has changed.

Remedy: Check that the correct path of the Gem is registered to your project. You can find the paths to a registered Gem in your project’s project.json configuration file under external_subdirectories. If necessary, update the Gem’s directory path, or clean up any obsolete paths.
