FOO_LIBRARIES can be set like this:

find_library(FOO1_LIBRARY_DEBUG NAMES foo1d ...)
find_library(FOO1_LIBRARY_RELEASE NAMES foo1 ...)
find_library(FOO2_LIBRARY_DEBUG NAMES foo2d ...)
find_library(FOO2_LIBRARY_RELEASE NAMES foo2 ...)
set(FOO1_LIBRARY debug ${FOO1_LIBRARY_DEBUG}
                 release ${FOO1_LIBRARY_RELEASE})
set(FOO2_LIBRARY debug ${FOO2_LIBRARY_DEBUG}
                 release ${FOO2_LIBRARY_RELEASE})
set(FOO_LIBRARIES ${FOO1_LIBRARY} ${FOO2_LIBRARY})

See FindQt4 for a non-trivial example of finding alot of libraries with
multiple configurations:

Where did you see this example on the Wiki?
