For libraries that came as RPM's use

  $ rpm -qa | grep fftw

Lots of civilized apps and libraries use the pkg-config system.  You
can just ask it and it tells you where it's installed, etc.

E.g., $ pkg-config --list-all

It will also tell you stuff about a particular package, such as
CFLAGS, library locations, etc.

E.g., $ pkg-config --cflags gnuradio-core
      $ pkg-config --libs gnuradio-core
