MGTwitterEngine error: yajl/yajl_parse.h no such file or directory

I'm using MGTwitterEngine in my project and when compiling the whole project I get 23 error which are all releated to yajl/yajl_parse.h no such file o开发者_JS百科r directory

Is there any solution for that?

Thanks!

The project only contains references to yajl. You have to plug it in by yourself.
