libraries

Hi, i generated my extension from the ext/ directory. i copied my extension dir in an other directory and i ran phpize to be able to compile it in standalone... Now, i need to link libcurl with it... only problem is if i set it in my config.m4 i don't have nothing anymore to make the changes to apply and the generated makefile is a mess for a human reader when it's generated by this tool. Anyone may tell me how i can link it ? can i make the changes of config.m4apply ? any other way ? Thank you :)
