+
+Distributions usually split libraries in several packages. The main package
+contains the files necessary to run programs using the library. The
+development package contains the files necessary to build programs using the
+library. Sometimes, docs and/or data are in a separate package too.

+To build FFmpeg, you need to install the development package. It is usually
+called @file{libfoo-dev} or @file{libfoo-devel}. You can remove it after the
+build is finished, but be sure to keep the main package.
