Please, where is my mistake ?

– I copy the Syphon.framework folder I found in jit.gl.syphonclient.mxo package into the Contents/Frameworks folder of the MaxMSP Runtime package ;
– I build my app including jit.openexr.mxo, I get this message in the max window :
Starting Build for syphonclient5.app…
