Theos libxml2: No such file or directory

I am using theos write settings and need to use libxml2. I added LDFLAGS like this:

widget_INSTALL_PATH = /Library/WeeLoader/Plugins/
widget_FRAMEWORKS = UIKit CoreGraphics
widget_LDFLAGS = -lxml2

      

        
        
        
      

    

code in my xxx.m

#import "BBWeeAppController-Protocol.h"
#import <libxml/HTMLparser.h>

      

        
        
        
      

    

than make, the error is:

error: libxml/HTMLparser.h: No such file or directory

      

        
        
        
      

    

in xcode need to set "header search path" -> $ SDKROOT / usr / include / libxml2, but how to do it in theos "?
