How to get boost libraries to link in cross compile?

edit

I cannot get my cross compile to link to the boost libraries in my buildroot.

How can I get catkin/cmake to find the correct libraries (using the arm native libraries in my buildroot instead of the i386 system libraries)? I have tried updating LD_LIBRARY_PATH, and CMAKE_PREFIX_PATH, but I still get linker errors:

/usr/lib/gcc/arm-linux-gnueabi/4.4.7/../../../../arm-linux-gnueabi/bin/ld: cannot find -lPocoFoundation
/usr/lib/gcc/arm-linux-gnueabi/4.4.7/../../../../arm-linux-gnueabi/bin/ld: cannot find -lboost_signals-mt
/usr/lib/gcc/arm-linux-gnueabi/4.4.7/../../../../arm-linux-gnueabi/bin/ld: cannot find -lboost_filesystem-mt
/usr/lib/gcc/arm-linux-gnueabi/4.4.7/../../../../arm-linux-gnueabi/bin/ld: cannot find -llog4cxx
/usr/lib/gcc/arm-linux-gnueabi/4.4.7/../../../../arm-linux-gnueabi/bin/ld: cannot find -lboost_regex-mt
/usr/lib/gcc/arm-linux-gnueabi/4.4.7/../../../../arm-linux-gnueabi/bin/ld: cannot find -lboost_date_time-mt
/usr/lib/gcc/arm-linux-gnueabi/4.4.7/../../../../arm-linux-gnueabi/bin/ld: cannot find -lboost_system-mt
/usr/lib/gcc/arm-linux-gnueabi/4.4.7/../../../../arm-linux-gnueabi/bin/ld: cannot find -lboost_thread-mt
/usr/lib/gcc/arm-linux-gnueabi/4.4.7/../../../../arm-linux-gnueabi/bin/ld: cannot find /lib/libpthread.so.0
/usr/lib/gcc/arm-linux-gnueabi/4.4.7/../../../../arm-linux-gnueabi/bin/ld: cannot find /usr/lib/libpthread_nonshared.a

I think this is because cmake does not like that there are multiple versions of this library on the system, even though I order them in the LD_LIBRARY_PATH!

-- catkin 0.5.86
-- Using these message generators: gencpp;genlisp;genpy
-- Boost version: 1.49.0
-- Found the following Boost libraries:
--   system
--   thread
-- Configuring done
CMake Warning at CMakeLists.txt:109 (add_library):
  Cannot generate a safe runtime search path for target gt_formation because
  files in some directories may conflict with libraries in implicit
  directories:

    runtime library [libPocoFoundation.so.9] in /usr/lib may be hidden by files in:
      /home/uav/rpi/rootfs/usr/lib
    runtime library [liblog4cxx.so.10] in /usr/lib may be hidden by files in:
      /home/uav/rpi/rootfs/usr/lib

  Some of these libraries may not be found correctly.

Yes, cmake, I know. I "hid" them on purpose. Why is it ignoring the CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY setting?

So, what is the correct way of forcing cmake to use the libs in the buildroot?

Here is my toolchain.cmake file:

set(CMAKE_SYSTEM_NAME Linux)
set(CMAKE_C_COMPILER arm-linux-gnueabi-gcc)
#$ENV{HOME}/rpi/tools/arm-bcm2708/arm-bcm2708-linux-gnueabi/arm-bcm2708-linux-gnueabi/bin/gcc)
set(CMAKE_CXX_COMPILER arm-linux-gnueabi-g++-4.4)
set(CMAKE_FIND_ROOT_PATH $ENV{HOME}/rpi/tools/arm-bcm2708/arm-bcm2708-linux-gnueabi/arm-bcm2708-linux-gnueabi/sysroot $ENV{HOME}/rpi/rootfs $ENV{HOME}/rpi/rootfs/e2fsprogs-1.42.9 $ENV{HOME}/rpi/rootfs/usr $ENV{HOME}/rpi/rootfs/usr/lib $ENV{HOME}/rpi/rootfs/usr/include $ENV{HOME}/rpi/ros_catkin_ws/install_isolated $ENV{HOME}/rpi/ros_catkin_ws/install_isolated/lib)
set(CMAKE_LIBRARY_PATH $ENV{HOME}/rpi/ros_catkin_ws/install_isolated $ENV{HOME}/rpi/ros_catkin_ws/install_isolated/lib)
set(BOOST_LIBRARYDIR /home/uav/rpi/rootfs/usr/lib)
set(Boost_LIBRARY_DIRS /home/uav/rpi/rootfs/usr/lib)
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM BOTH)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

Thanks in advance!
