This code uses a trivial function to illustrate adding tests and collect statement coverage with makefiles. To use this in Linux, you will need
sudo apt-get install -y libgtest-dev lcov cd /usr/src/gtest sudo cmake CMakeLists.txt sudo make sudo cp *.a /usr/lib
The files:
make -f SmallerMakefile(or simply rename it to Makefile)
sudo apt-get install -y g++ cmake libgtest-dev lcov cd /usr/src/gtest sudo cmake CMakeLists.txt sudo make sudo cp *.a /usr/lib
