# TODO 3: Install Tutorial in the bin directory
# Hint: Use the TARGETS and DESTINATION parameters

# TODO 4: Install TutorialConfig.h to the include directory
# Hint: Use the FILES and DESTINATION parameters

# TODO 5: Enable testing

# TODO 6: Add a test called Runs which runs the following command:
# $ Tutorial 25

# TODO 7: Add a test called Usage which runs the following command:
# $ Tutorial
# Make sure the expected output is displayed.
# Hint: Use the PASS_REGULAR_EXPRESSION property with "Usage.*number"

# TODO 8: Add a test which runs the following command:
# $ Tutorial 4
# Make sure the result is correct.
# Hint: Use the PASS_REGULAR_EXPRESSION property with "4 is 2"

# TODO 9: Add more tests. Create a function called do_test to avoid copy +
# paste. Test the following values: 4, 9, 5, 7, 25, -25 and 0.0001.
