This is a visual unit test where the generate_examples target will run all other executables from the examples directory and save the resulting images to the documentation/examples directory.

Everytime we update the library, we regenerate the examples to make sure everything is not only working ok but also looking good.

The library needs to be compiled with the CMake option MATPLOTPP_BUILD_FOR_DOCUMENTATION_IMAGES for this test to work. Also, you need to run this target from the project root directory so that the filesystem can find the build and documentation directories.
