| # - Configure a project for downloading test data from a Girder server | ||
| # Include this module in the top CMakeLists.txt file of a project to | ||
| # enable downloading test data from Girder. Requires CTest module. | ||
| # project(MyProject) | ||
| # ... | ||
| # include(CTest) | ||
| # include(Girder3) | ||
| # | ||
| # To use this module, set the following variable in your script: | ||
| # Girder_REST_URL - URL of the Girder server's REST API | ||
| # Other optional variables: | ||
| # Girder_DATA_DIR - Where to place downloaded files | ||
| # - Defaults to PROJECT_BINARY_DIR/Girder_Data | ||
| # Girder_KEY_DIR - Where the key files are located | ||
| # - Defaults to PROJECT_SOURCE_DIR/Girder_Keys | ||
| # Girder_DOWNLOAD_TIMEOUT - Timeout for download stage (default 0) | ||
| # ---------------------- Authentication ------------------------- | ||
| # For authenticated access, you must also have the following variables set | ||
| # Girder_USER - The email of the user to authenticate as | ||
