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.
