Why not:
FIND_LIBRARY(NAMES kdewin32 kdewin32_d ...)

However, if there are two different types of libs, you will want to 
store them in separate
variables anyway.  As you will have to use them differently.

FIND_LIBRARY(kdewin32  KDEWIN32LIB)
FIND_LIBRARY(kdwin32_d KDEWIN32LIB_D)

...
target_link_libraries(foo optimized ${KDEWIN32LIB} debug ${KDEWIN32LIB_D})
