There are add-on IDE's.

For example, have a look at http://cedet.sourceforge.net  for C/C++ development,
or at http://common-lisp.net/project/slime for Common Lisp development.


For the specific feature you ask, you can build a TAGS file for your
project, scanning all the source and header files with the etags
command, and using the find-tag command (M-.) to find definitions, etc.

For example, I put this target in my Makefile:

etags tags:
        find $$(pwd) \( -name \*.lisp \
                                        -o -name \*.[hc] \
                                        -o -name \*.hh -o -name \*.cc \
                                \) -print | etags -

M-x tags-reset-tags-table RET
M-x compile RET tags RET

Then I type the name of a function and M-.
it asks for confirmation of the name of the function,
and for the path to the TAGS file built by make tags above, (the first
time after a tags-reset-tags-table), and the goes to the definition.
