How to include needed C library using gcc?

I am trying to compile the simple C example from this Tutorial on Ubuntu using gcc. What do I have to use as argument for gcc to include the needed libraries for #include <libappindicator/app-indicator.h>?


-I<search path to include files>
-L<search path to the lib file>
-l<libname>

Use the -l command line option. You can specify the library search path with the -L option. E.g:

gcc -o myprogram -lfoo -L/home/me/foo/lib myprogram.c

This will link myprogram with the static library libfoo.a in the folder /home/me/foo/lib.
