Why should it look into the prefix you passed to configure? The prefix
you specify there is where you want your software to be installed. It
is unrelated to the prefix libraries and header files should be taken
from. Of course you can choose to have them searched in the same
prefix and that's what PKG_CONFIG_PATH allows you to do.
