# Dependencies

# For downloading and building required dependencies
include(FetchContent)

# Google Test (https://github.com/google/googletest)
# NOTE: Google Test has created a mess with legacy FindGTest.cmake and newer GTestConfig.cmake
#
# FindGTest.cmake defines:   GTest::GTest, GTest::Main, GTEST_FOUND
#
# GTestConfig.cmake defines: GTest::gtest, GTest::gtest_main, GTest::gmock, GTest::gmock_main
#
# NOTE2: Finding GTest in MODULE mode, one cannot invoke find_package in CONFIG mode, because targets
#        will be duplicately defined.
