How can I get gcc to find certain libraries?

I am trying to compile a program (gcc, using some functions from intel's ipp library).
It is my first use of ipp, so I think I might be doing some not very clever mistake. Anyhow:

g++ -o inteltrial inteltrial.cpp -I/home/me/Desktop/work/p1/geqw4/vi3/out/sp/ccode/eigen -I/opt/intel/composerxe/ipp/include -L/opt/intel/composerxe/ipp/lib/intel64/ -libipps_l.a -libipps_t.a

gives:

/usr/bin/ld: cannot find -libipps_l.a

/usr/bin/ld: cannot find -libipps_t.a

now, -libipps_l.a -libipps_t.a are in /opt/intel/ipp/lib/intel64

How to point gccto the right location?

EDIT:

This post seems to be related, but I can't find on the internet how
to add a line to ld.so.conf....

this did the trick:

IPPROOT=/opt/intel/ipp

export IPPROOT

cd /home/me/Desktop/work/p1/geqw4/vi3/out/sp/ccode

icpc -O3 -o inteltrial inteltrial.cpp -I/home/me/Desktop/work/p1/geqw4/vi3/out/sp/ccode/eigen -I$IPPROOT/include -L$IPPROOT/lib/intel64 -lipps -lippcore
