Then following your way it should be enough to do define
ITK_DIR and ELASTIX_BUILD depending on CMAKE_BUILD_TYPE, which
should be something like:

IF (CMAKE_BUILD_TYPE STREQUAL "Debug")
    SET(ITK_DIR ${EXTERNALS_DIR}/InsightToolkit-3.12.0/build)
    SET(ELASTIX_BUILD ${EXTERNALS_DIR}/elastix_sources_v4.1/src/build)
ENDIF (CMAKE_BUILD_TYPE STREQUAL "Debug")

IF (CMAKE_BUILD_TYPE STREQUAL "Release")
    SET(ITK_DIR ${EXTERNALS_DIR}/InsightToolkit-3.12.0/buildRelease)
    SET(ELASTIX_BUILD ${EXTERNALS_DIR}/elastix_sources_v4.1/src/buildRelease)
ENDIF (CMAKE_BUILD_TYPE STREQUAL "Release")

However since ITK and may be ELASTIX seems to be build with CMake
you should have look at:
http://www.itk.org/Wiki/CMake:ExportInterface

which may be a better way to use "external" libraries.
