To use googletest on OpenBSD, I need to install CMake firstly:
# pkg_add cmake
Then Download googletest and create build directory:
# git clone https://github.com/google/googletest.git
# cd googletest
# mkdir build
# cd build
If use default gcc compiler, the compilation will generate following errors:
# make
[ 2%] Building CXX object googlemock/CMakeFiles/gmock.dir/__/googletest/src/gtest-all.cc.o
cc1plus: warnings being treated as errors

*** Error 1 in . (googlemock/CMakeFiles/gmock.dir/build.make:63 'googlemock/CMakeFiles/gmock.dir/__/googletest/src/gtest-all.cc.o': cd /root...)
*** Error 1 in . (CMakeFiles/Makefile2:90 'googlemock/CMakeFiles/gmock.dir/all')
*** Error 1 in /root/Project/googletest/build (Makefile:139 'all')
So I switch to clang, and all build is OK:
# CC=clang cmake ..
# make
# make install
