Description of Change

Checklist

• Added description

GTest exports the following targets:

• GTest::gtest
• GTest::gtest_main
• GTest::gmock
• GTest::gmock_main

This targets should also be available when adding gtest with add_subdirectory (or FetchContent), because this should behave the same way as adding GTest with find_package. So somewhere, we should add the aliases to these targets, i.e.

add_library(GTest::gtest ALIAS 

As discussed in #3926, the following files do not have .py extensions because TensorFlow does not yet support the current Python.

• dynamic_programming/k_means_clustering_tensorflow.py_tf
• machine_learning/lstm/lstm_prediction.py_tf
• neural_network/gan.py_tf
• neural_network/input_data.py_tf

TODO: Restore the .py file extensions
