===================================== Windows Dependancy Build Instructions

Note for VS 2010, 2013, and 2015 these are already made for you. Nothing more need be done.

Build requirements

From the Visual Studio command prompt
- Unzip libpng at lpng1256/: unzip lpng1256.zip
- set INCLUDE=%INCLUDE%;Z:\path\to\openitg\src\zlib
- from the lpng1256 dir, run: nmake /f .\scripts\makefile.vcwin32
From the repository root in a mingw-w32 shell (.\msys2_shell.cmd -mingw32 -full-path)
- Install build dependencies: pacman -S unzip diffutils yasm make mingw32/mingw-w64-i686-gcc
- Untar ffmpeg at ffmpeg-3.0.3/ and cd into it: tar -zxvf ffmpeg-3.0.3.tar.gz; cd ffmpeg-3.0.3
- run ./configure --prefix=../ffmpeg-build --enable-shared --toolchain=msvc --cpu=opteron, wait forever (Note --cpu=opteron is used to work around incorrect detection of processors having FAST_CLZ)
- make && make install
- cp ../ffmpeg-build/bin/*.dll ../Program
Move compiled libs to proper location in extern folder
Follow Directions on building windows release from the normal readme
To build the installer, from cmd or powershell
