CMakeLists.txt

# Thanks to https://github.com/dmonopoly/gtest-cmake-example/blob/master/CMakeLists.txt
# for providing a basic setup to use gtest in a cmake project
# Another solution would make use of ExternalProject_Add to downloads and installs
# googletest in the build/ dir:
# http://stackoverflow.com/questions/9689183/cmake-googletest/9695234#9695234
# However, this requires an active internet connection
