# TODO5: Add the targets from TODO2 to the TutorialTargets export

# TODO6: Install the TutorialTargets export to:
#          ${CMAKE_INSTALL_LIBDIR}/cmake/Tutorial
#        And give them a namespace of "Tutorial::"

# TODO10: Include CMakePackageConfigHelpers

# TODO11: Use write_basic_package_version_file to write a
#         TutorialConfigVersion.cmake file to the CMAKE_CURRENT_BINARY_DIR.
#         The version compatibility should be ExactVersion.

# TODO12: Add the generated TutorialConfigVersion.cmake file to the file list
#         of the TODO7 install() command.

# TODO7: Install the config file at cmake/TutorialConfig.cmake to the same
#        destination as the TutorialTargets export.
