This is a header-only library and needs no runtime binary. But the unit tests require building runtime. Use cmake to build the googletest C++ code:
$ SRC_PATH=`pwd`
$ BUILD_PATH=/some/place
$ cd ${BUILD_PATH}
$ cmake ${SRC_PATH}
$ cd ${SRC_PATH}
$ cmake -DCMAKE_BUILD_TYPE=Release ${BUILD_PATH}; make -C ${BUILD_PATH} run_gtest
-- Configuring done
-- Generating done
-- Build files have been written to: ${BUILD_PATH}

If you want to build the debug version, replace CMAKE_BUILD_TYPE in the the
last command:
$ cmake -DCMAKE_BUILD_TYPE=Debug ${BUILD_PATH}; make -C ${BUILD_PATH}
