Cmake Alembic detection script needs to recognize newer Alembic builds.

[meshula]

On Windows, Alembic no longer builds to many small libraries, instead only a single DLL and lib are generated.

That means that the detection should look something like this:

    find_library(ALEMBIC_LIBRARY
                 NAMES Alembic
                 PATHS ${LIBRARY_PATHS})

    set(ALEMBIC_LIBRARIES ${ALEMBIC_LIBRARY})

    get_filename_component(ALEMBIC_LIBRARY_DIR ${ALEMBIC_LIBRARY} PATH)

A possible solution would be to add a detection phase in the Cmake script, along the lines of

if (NOT ALEMBIC_ABC_LIBRARY_FOUND)
   message("Historic Alembic not detected, looking for modern Alembic")
   .... then do something like what I listed above.
endif()

Nick,

I believe this only applies to the latest version. But agreed, it would be nice if we are to support versions > 1.5.2.

Yep, I think this affects versions >= 1.6.0 , per alembic/alembic@834eca6

I can take a look at this.
