Hello, ... i plan to package a program called mozart, that uses gmp version 2 and searches his includes under /usr/include/gmp.h and his libs under /usr/lib/libgmp.so but since both gmp1 and gmp2 are supported under debian, gmp2 stuff are in /usr/include/gmp2/gmp.h, and the libraries are/usr/lib/libgmp2.so How do i tell the autostuff how to search for the library in the right place ?
