Background: I'm trying to build my program but first I need to set up libraries in netbeans. My project is using GLU and therefore I installed libglu-dev. I didn't note location where the libraries were located and now I can't find them..

I've switched to Linux just a few days ago and so far I'm very content with it, however I couldn't google this one out and becoming frustrated.. Is there way to find out where files of package were installed without running installation again? I mean if I got library xxx and installed it some time ago, is there somecommand xxx that will print this info?

I've already tried locate, find and whereis commands but either I'm missing something or I just can't do it correctly.. for libglu, locate returns:

/usr/share/bug/libglu1-mesa
/usr/share/bug/libglu1-mesa/control
/usr/share/bug/libglu1-mesa/script
/usr/share/doc/libglu1-mesa
/usr/share/doc/libglu1-mesa/changelog.Debian.gz
/usr/share/doc/libglu1-mesa/copyright
/usr/share/lintian/overrides/libglu1-mesa
/var/lib/dpkg/info/libglu1-mesa:i386.list
/var/lib/dpkg/info/libglu1-mesa:i386.md5sums
/var/lib/dpkg/info/libglu1-mesa:i386.postinst
/var/lib/dpkg/info/libglu1-mesa:i386.postrm
/var/lib/dpkg/info/libglu1-mesa:i386.shlibs

Other two commands fail to find anything. Now locate did it's job but I'm sure none of those paths is where the library actually resides (at least everything I was linking so far was in /usr/lib or usr/local/lib).

The libglu was introduced just as example, I'm looking for general solution for this problem.
