janus-gateway用cmake实现

 假如janus-gateway需要添加ffmpeg的支持，可以参考下面的实现方式，用CMakeList.txt 实现

cmake_minimum_required(VERSION 2.8)
project(janus)

find_package(PkgConfig REQUIRED)
pkg_check_modules(GLIB_PKG glib-2.0)

if (GLIB_PKG_FOUND)
    message(Found glib-2.0)
    include_directories(${GLIB_PKG_INCLUDE_DIRS})
endif ()

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
