When the option "autodeps" is enabled, makepkg will add provides entries for libraries found in the directories specified in LIB_DIRS in makepkg.conf. The entries LIB_DIRS array have the format "prefix:directory". For example, the entry "lib:usr/lib" will search $pkgdir/usr/lib for library sonames and add "lib:libfoo.so.1" to the provides array.
