Cocos2d-x iOS Mac环境编译出错 can't locate file for: -lpng -ljpeg -ltiff -lwebp -lfreetype -lwebsockets -lcurl
在Mac上用Xcode6编译错误，在windows下面Visual Studio 编译没问题，然后查看报错信息：

原因其实很简单，就是Cocod2d-x的Mac和iOS静态库没有搜索到，
一般是使用svn客户端没有正确上传.a导致的，
解决方法：把找到对应版本的Cocod2d-x相应目录下面的.a文件复制到相应目录下，
然后把.a的静态库添加到svn的版本控制里面；
使用命令
svn add 路径/静态库.a
iOS的库文件路径如下：
/opt/cocos2d-x-3.2> find . -type f | grep -i ios/lib
./external/curl/prebuilt/ios/libcurl.a
./external/freetype2/prebuilt/ios/libfreetype.a
./external/jpeg/prebuilt/ios/libjpeg.a
./external/lua/lua/prebuilt/ios/liblua.a
./external/lua/luajit/prebuilt/ios/libluajit.a
./external/png/prebuilt/ios/libpng.a
./external/tiff/prebuilt/ios/libtiff.a
./external/webp/prebuilt/ios/libwebp.a
./external/websockets/include/ios/libwebsockets.h
./external/websockets/prebuilt/ios/libwebsockets.a
./plugin/plugins/flurry/proj.ios/libFlurry.a
./plugin/plugins/umeng/proj.ios/libMobClickLibrary.a
