Summary:                    ExternalProject commands do not support generator
expressions
Description: 
ExternalProject_* does not support generator expressions. For projects such as
boost, "variant" can be set to debug or release. However, ${CONFIG} will be
either Debug or Release (note case).


Example being:
ExternalProject_Add(
    boost
    DOWNLOAD_COMMAND  snip
    SOURCE_DIR # snip
    BUILD_IN_SOURCE 1
    UPDATE_COMMAND ""
    PATCH_COMMAND ""
    CONFIGURE_COMMAND ${BOOST_BOOTSTRAP_COMMAND}
    BUILD_COMMAND
        b2 variant=$<LOWER_CASE:$<CONFIG>>
    INSTALL_COMMAND ""
    LOG_DOWNLOAD 1
    LOG_CONFIGURE 1
    LOG_BUILD 1
)

It's true the generator expressions might not always be sufficient, but would
certainly help.
