Build FFmpeg static lib in Window using MSYS2 and MSVC 2017

gistfile1.txt

It's take two day searching and trying to firgure out the correct way =)))

follow https://trac.ffmpeg.org/wiki/CompilationGuide/WinRT

-------BUT IT'S NOT WORK--------

1. Make sure SET LIB ; SET LIBPATH ; SET INCLUDE with exist and right path(version, exist binary files...)
2. Make sure evironment path, environment variables point to right value/path.

--------If still cannot build, follow my way---------

1. Follow MSYS2 Setup in https://trac.ffmpeg.org/wiki/CompilationGuide/WinRT

2. Make sure add PATH C:\msys64\ in environment system variable to run msys2_shell.cmd everywhere

3. Edit C:/msys64/msys2_shell.cmd
	Add these line below the "setlocal (or setlocal EnableDelayedExpansion line)"

	call "%VS150COMNTOOLS%..\..\VC\Auxiliary\Build\vcvarsall.bat" x86 store
	set LIB=%VS150COMNTOOLS%..\..\VC\Tools\MSVC\%VCToolsVersion%\lib\x86;%UniversalCRTSdkDir%Lib\%UCRTVersion%\ucrt\x86;%UniversalCRTSdkDir%Lib\%UCRTVersion%\um\x86;
	set LIBPATH=%VS150COMNTOOLS%..\..\VC\Tools\MSVC\%VCToolsVersion%\lib\x86;
	set INCLUDE=%VS150COMNTOOLS%..\..\VC\Tools\MSVC\%VCToolsVersion%\include;%VS150COMNTOOLS%..\..\VC\Tools\MSVC\%VCToolsVersion%\atlmfc\include;%UniversalCRTSdkDir%Include\%UCRTVersion%\ucrt;%UniversalCRTSdkDir%Include\%UCRTVersion%\um;%UniversalCRTSdkDir%Include\%UCRTVersion%\shared;%UniversalCRTSdkDir%Include\%UCRTVersion%\winrt;

4. Make sure SET LIB ; SET LIBPATH ; SET INCLUDE above are OK(version, exist binary files...)
   also %VS150COMNTOOLS% environment variable point to right dir.

5. Maybe you also need to add system environment PATH C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.16.27023\bin\Hostx64\x86

6. Open cmd.exe and call msys2_shell.cmd -use-full-path (it will pass above config to msys instance)

7. In msys terminal, cd to ffmpeg and call your configure/make/make install
   Here is my example configure
   
--configure.sh file--
#!/bin/sh
./configure \
