下载msys2
下载libpng源码
下载mingw
安装过程略，注意mingw要添加到系统的环境变量
启动msys2脚本msys2_shell.bat
需要继承windows系统的环境变量，三种方法选择一个就可以：
msys2_shell.cmd 中取消一行的注释：set MSYS2_PATH_TYPE=inherit
调用msys2_shell.cmd时使用-use-full-path参数
在windows系统的环境变量中添加 MSYS2_PATH_TYPE=inherit
测试环境搭建成功
$ g++ -dumpversion
4.9.4
能够输出mingw-g++版本说明正确
切换到libpng源码目录
$ cd /C/Users/m/Downloads/libpng-1.2.56.tar/libpng-1.2.56/
配置
./configure --prefix=/usr/local/libpng/
--prefix=/usr/local/libpng/ 指定了安装libpng到/usr/local/libpng/目录
其它的参数如
--enable-shared[=PKGS] build shared libraries [default=yes]
--enable-static[=PKGS] build static libraries [default=yes]
下面是配置过程的输出

如果你的msys安装了pkg-config，可以查看编译链接参数
查看PKG_CONFIG_PATH
$ echo $PKG_CONFIG_PATH
/usr/lib/pkgconfig:/usr/share/pkgconfig:/lib/pkgconfig
把libpng库目录里的lib/pkgconfig/下面的pc文件拷贝到/usr/lib/pkgconfig/目录
之后查看编译链接参数
$ pkg-config --cflags --libs libpng12
-ID:/BuildChanTools/msys64/usr/include/libpng12 -LD:/BuildChanTools/msys64/usr/lib -lpng12
编译完成了
注意
msys的文件系统路径在安装目录下（/usr,/home,/etc,/dev...）
使用测试
g++ test.cpp -ID:/BuildChanTools/msys64/usr/include/libpng12 -LD:/BuildChanTools/msys64/usr/lib -lpng12 -o test.exe
./test.exe
