To elaborate on this a little -- In general, a package libfoo includes the library necessary to run a program compiled against that library, but not any files needed to actually compile that program. I find I almost never need to install a library like this directly, since any programs using it will have it as a dependency. The corresponding libfoo-dev package will include the needed header and other files (including libfoo.pc) needed to compile a program making use of the library. It will normally have libfoo as a dependency, so installing libfoo-dev will be all you need to do manually to be able to compile against and use libfoo.
