Some options:
1. When compiling yourself on a Debian based system use checkinstall
where possible. This creates a local deb file and installs via the
package manager.

2.In you particular case /usr/local/lib just isn't in the normal path.
You can either add it to the path via a command line statement or using
the ldconfig system, OR you can specifiy directories to be included in
the ffmpeg build process. It's usually something like
--include=/usr/local/lib/ but check the docs of configure and the ffmpeg
package.
