• cmake -Dgtest_build_samples=ON -Dgtest_build_tests=ON ~/googletest
• make
• make test
• ./googlemock/gtest/sample1_unittest

Install the googletest and googlemock .a and .h files:

• sudo cp -r -v ~/googletest/googletest/include/gtest /usr/local/include
• sudo cp -r -v ~/googletest/googlemock/include/gmock /usr/local/include
• sudo cp -v ~/googletest/build/googlemock/lib*.a /usr/local/lib
• sudo cp -v ~/googletest/build/googlemock/gtest/lib*.a /usr/local/lib
