I use the following options to compile with system's clhep (or a local
installation of CLHEP that may be located anywhere as long as the path
is provided):

    -DGEANT4_USE_SYSTEM_CLHEP=ON \
    -DCLHEP_CONFIG_EXECUTABLE=${prefix}/bin/clhep-config \
    -DCLHEP_INCLUDE_DIR=${prefix}/include \
    -DCLHEP_LIBRARY=${prefix}/lib/libCLHEP.dylib

(where you need to replace ${prefix} with the actual place where you
have CLHEP installed).

The following is not true:

This used to be the case in Gate a while ago (not in Geant4), but Gate
fixed this recently as well.

If you want to build the built-in CLHEP, you actually need to run
    [c]cmake ../geant4.9.5-p02 -DGEANT4_USE_SYSTEM_CLHEP=OFF
or set that variable in the installer. But last time I tried, the
built-in CLHEP from Geant4 wasn't sufficient for Gate for some reason.

It doesn't help you to export PATH and LD_LIBRARY_PATH. You need to
set the proper variables either in ccmake or as command-line arguments
to cmake.
