linking your executable to those libs or are you doing
something like "dlopen" inside your application?

Are your speaking of this page:
http://www.cmake.org/Wiki/CMake_RPATH_handling ?

If yes it usually works for me with:

# use, i.e. don't skip the full RPATH for the build tree
SET(CMAKE_SKIP_BUILD_RPATH  FALSE)

# when building, don't use the install RPATH already
# (but later on when installing)
SET(CMAKE_BUILD_WITH_INSTALL_RPATH FALSE)

Which version of CMake ?
What is you platform ?

Supposing your are on Linux
Does it work if you setup LD_LIBRARY_PATH by hand?
Could you run
$ ldd yourapplication
