Install googletest on OpenBSD

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 . (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

Build googlemock library

When enabling ENABLE_TESTS option to build tfhe project, the googlemock library is needed, otherwise the following errors will be generated:

[ 54%] Linking CXX executable unittests-fftw
/usr/bin/ld: cannot find -lgmock
collect2: error: ld returned 1 exit status
make[2]: *** [test/CMakeFiles/unittests-fftw.dir/build.make:229: test/unittests-fftw] Error 1
make[1]: *** [CMakeFiles/Makefile2:1290: test/CMakeFiles/unittests-fftw.dir/all] Error 2
make: *** [Makefile:95: all] Error 2

To build googlemock, you can follow this guide:

(1) Download googletest:

$ git clone https://github.com/google/googletest.git

(2) Execute autoreconf command:

$ cd googletest/googlemock
$ autoreconf -fvi

(3) Create libgmock:

$ cd make
$ make
$ ar -rv libgmock.a gtest-all.o gmock-all.o

(4) Copy libgmock.a into /usr/local/lib:

$ cp libgmock.a /usr/local/lib/

Then you can use libgmock.a now.
