编译obs

- NOTE: OBS on windows currently requires VS2013, as obs-studio uses C99 and

    C++11.  Express might not be supported at this time (though I'll fix it at

    some point).

  - Clone the repo.  After cloning, run the following git commands:

        git submodule init

        git submodule update

    which will download submodules.     必须完整下载，包括依赖文件

  - Download (or build) development packages of FFmpeg, x264, Qt5.

  - Download windows version of cmake from: http://www.cmake.org/

  - Add windows environment variables:

        FFMpegPath    (path to FFmpeg include directory)

        x264Path      (path to x264 include directory)

        QTDIR         (path to Qt build base directory)

1、ffmpeg问题

 修改FindFFMpeg.cmake文件，在下面的位置加入以下内容：

###########
	# find_path  
	find_path(FFMPEG_${component}_INCLUDE_DIR  
	  NAMES 
			"lib${component}/${header}" "lib${component}/version.h"
	  PATHS 
			"G:/qt/sdk/ffmpeg-20141016-git-0e406ab-win32-dev/include"  
	)  
	#find_library
	find_path(FFMPEG_${component}_INCLUDE_DIR  
	  NAMES 
			"${component}" "lib${component}"
	  PATHS 
			"G:/qt/sdk/ffmpeg-20141016-git-0e406ab-win32-dev/lib"  
	)  
	############
           

2、x264问题

修改FindLibx264.cmake文件，在下面位置加入以下内容：

###########
	# find_path  
	find_path(X264_INCLUDE_DIR  
	  NAMES 
			x264.h
	  PATHS 
			"G:/project/OBS-master/x264"  
	)  
	#find_library
	find_path(X264_LIB  
	  NAMES 
			${_X264_LIBRARIES} x264 libx264.lib
	  PATHS 
			"G:/project/OBS-master/x264/libs/32bit"
	)
