Thank you for the suggestion.  Setting EXECUTABLE_OUTPUT_PATH
would solve the problem for finding the executables.  

Is there a way to set the ITK dll path?  It is something like 
${ITK_LIBRARY_DIRS}/Release or ${ITK_LIBRARY_DIRS}/Debug.
CTest is run with something like "-C Release" or "-C Debug", 
Is there a way to substitute this in?  My CMake test looks like 
this (hard-coded version):

ADD_TEST (${TESTNAME} ${CMAKE_COMMAND} 
     -DITK_LIBRARY_PATH=${ITK_LIBRARY_DIRS}/Release
     -DPLM_TEST_COMMAND=${PLM_TEST_COMMAND}
     -P ${CMAKE_CURRENT_SOURCE_DIR}/RUN_CTEST.cmake
     )
