Build steps for i686 architecture:
1. unzip mingw.7z to C:\mingw
2. unzip qt.7z to C:\qt
3. download and install cmake from https://cmake.org/download/
2. Prepare environment
	- set prefix for mingw e.g.: for C:\mingw\7_1_x32\
		set SDK_MINGW_DIR=C:\mingw\7_1_x
	- set prefix for Qt5 e.g.: for C:\qt\qt5120_win32\
		set SDK_QT5_DIR=C:\qt\qt5120_win
	- set SDK_CMAKE_DIR=C:\cmake
4. run make_libs32.bat

Build steps for amd64 architecture:
 -- follow previos steps, but replace '32' to '64'
 
Build steps for both architectures:
	-- follow previos steps, but on '4' state run make_libs_all.bat
