Tried a lot of CMAKE options, but could not get it right. The Wl,-R
options appear correct in the configuration generated, but simply refuses
to reflect in the binaries. As a last resort I am patching the RPATH.

    +RASPI_PREFIX=  ${PREFIX}/raspi
     SUBST_CLASSES+=                vc
     SUBST_STAGE.vc=                pre-configure
     SUBST_MESSAGE.vc=      Fixing hard-coded install paths.
     SUBST_FILES.vc=                makefiles/cmake/vmcs.cmake
    -SUBST_SED.vc=          -e 's,/opt/vc,${PREFIX},g'
    +SUBST_SED.vc=          -e 's,/opt/vc,${RASPI_PREFIX},g'
    +
    +TOOL_DEPENDS+=      patchelf-[0-9]*:../../devel/patchelf
    +
    +FIX_RPATH+=    ${DESTDIR}${RASPI_PREFIX}/bin/*
    +FIX_RPATH+=    ${DESTDIR}${RASPI_PREFIX}/sbin/*
    +FIX_RPATH+=    ${DESTDIR}${RASPI_PREFIX}/lib/*.so
    +FIX_RPATH+=    ${DESTDIR}${RASPI_PREFIX}/lib/plugins/*.so
    +
    +post-install:
    +       for bin in ${FIX_RPATH}; do \
    +               echo $$bin; \
    +               ${PREFIX}/bin/patchelf --set-rpath ${RASPI_PREFIX}/lib $$bin; \
    +       done
    +

Any suggestions for a simpler solution are welcome.
