This is small tips on how to build Google protobuf on windows using mingw 8.1. You can skip from
reading this tutorial and download from their binaries release instead for convenience.
Before digging into deeper compilation steps, please make sure that you had already installed of all the following tools:
If all of above tools is already present, then we can continue to our build process.

The problem is that gcc treats -isystem differently than usual -I flag. So, to fix that we make sure append following additional cmake command
for 32 build and for 64 build is like follows :
At the end, the following command is appropriate for 32 build:
cmake.exe -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES=%MINGWPATH%\i686-w64-mingw32\include -DCMAKE_INSTALL_PREFIX=%MINGWPATH%\opt ..\protobuf\cmake -G "MinGW Makefiles" && mingw32-make && mingw32-make install
I hope you enjoy it, thanks for reading.
