x265静态编译win10--

msys2的mingw环境：
1.拉取x265源码

git clone https://github.com/videolan/x265.git -b 3.4cd x265

2.修改文件
修改source/CMakeLists.txt的内容，否则配置命令会失败：
将如下内容：

cmake_policy(SET CMP0025 OLD)cmake_policy(SET CMP0054 OLD)

改成：

cmake_policy(SET CMP0025 NEW)cmake_policy(SET CMP0054 NEW)

3.执行相关命令

cd build/msyscmake -G "MSYS Makefiles" ../../source -DCMAKE_POLICY_VERSION_MINIMUM=3.5 -DCMAKE_INSTALL_PREFIX=`pwd`/x265_install   -DENABLE_SHARED=OFF -DENABLE_STATIC=ON -DBUILD_SHARED_LIBS=OFFmake -j16make install
