This actually exists in lib/share/pkgconfig/PETSc.pc. This is okay if there will be only one version of PETSc installed to a standard location, but not if you want multiple installs (debug/opt, mpich/openmpi, etc.). I wish there was an established convention for this. We actually ensure that debug and opt have the same ABI so the user can switch them using LD_PRELOAD or LD_LIBRARY_PATH.
