If I am understanding correctly, you are looking for a debug version
of a library. If you can not find that library, then you default to
using the non-debug version of the library?
If that is the case then there are some CMake macros that might help.
I grabbed one from either the FindQt4 or the FindBoost and tweaked it
for my needs.
############################################
#
# Check the existence of the libraries.
#
############################################
# This macro was taken directly from the FindQt4.cmake file that is
included
# with the CMake distribution. This is NOT my work. All work was done
by the
# original authors of the FindQt4.cmake file. Only minor
modifications were
# made to remove references to Qt and make this file more generally
applicable
########################################################################

MACRO (_MXA_ADJUST_LIB_VARS basename)
IF (${basename}_INCLUDE_DIR)
# if only the release version was found, set the debug variable
also to the release version
IF (${basename}_LIBRARY_RELEASE AND NOT ${basename}_LIBRARY_DEBUG)
SET(${basename}_LIBRARY_DEBUG ${${basename}_LIBRARY_RELEASE})
SET(${basename}_LIBRARY ${${basename}_LIBRARY_RELEASE})
SET(${basename}_LIBRARIES ${${basename}_LIBRARY_RELEASE})
ENDIF (${basename}_LIBRARY_RELEASE AND NOT ${basename}_LIBRARY_DEBUG)
# if only the debug version was found, set the release variable
also to the debug version
IF (${basename}_LIBRARY_DEBUG AND NOT ${basename}_LIBRARY_RELEASE)
SET(${basename}_LIBRARY_RELEASE ${${basename}_LIBRARY_DEBUG})
SET(${basename}_LIBRARY ${${basename}_LIBRARY_DEBUG})
SET(${basename}_LIBRARIES ${${basename}_LIBRARY_DEBUG})
ENDIF (${basename}_LIBRARY_DEBUG AND NOT ${basename}_LIBRARY_RELEASE)
IF (${basename}_LIBRARY_DEBUG AND ${basename}_LIBRARY_RELEASE)
# if the generator supports configuration types then set
# optimized and debug libraries, or if the CMAKE_BUILD_TYPE has
a value
IF (CMAKE_CONFIGURATION_TYPES OR CMAKE_BUILD_TYPE)
SET(${basename}_LIBRARY optimized ${${basename}
_LIBRARY_RELEASE} debug ${${basename}_LIBRARY_DEBUG})
ELSE(CMAKE_CONFIGURATION_TYPES OR CMAKE_BUILD_TYPE)
# if there are no configuration types and CMAKE_BUILD_TYPE has
no value
# then just use the release libraries
SET(${basename}_LIBRARY ${${basename}_LIBRARY_RELEASE} )
ENDIF(CMAKE_CONFIGURATION_TYPES OR CMAKE_BUILD_TYPE)
SET(${basename}_LIBRARIES optimized ${${basename}
_LIBRARY_RELEASE} debug ${${basename}_LIBRARY_DEBUG})
ENDIF (${basename}_LIBRARY_DEBUG AND ${basename}_LIBRARY_RELEASE)
SET(${basename}_LIBRARY ${${basename}_LIBRARY} CACHE FILEPATH "The
${basename} library")
IF (${basename}_LIBRARY)
SET(${basename}_FOUND 1)
ENDIF (${basename}_LIBRARY)
ENDIF (${basename}_INCLUDE_DIR )
# Make variables changeble to the advanced user
MARK_AS_ADVANCED(${basename}_LIBRARY ${basename}_LIBRARY_RELEASE $
{basename}_LIBRARY_DEBUG ${basename}_INCLUDE_DIR )
ENDMACRO (_MXA_ADJUST_LIB_VARS)
I use the above in the following manner:
# Look for the library.
FIND_LIBRARY(EXPAT_LIBRARY_DEBUG
NAMES ${EXPAT_SEARCH_DEBUG_NAMES}
PATHS ${EXPAT_LIB_SEARCH_DIRS}
NO_DEFAULT_PATH
)
FIND_LIBRARY(EXPAT_LIBRARY_RELEASE
NAMES ${EXPAT_SEARCH_RELEASE_NAMES}
PATHS ${EXPAT_LIB_SEARCH_DIRS}
NO_DEFAULT_PATH
)
# include the macro to adjust libraries
INCLUDE (${MXA_RESOURCES_DIR}/MXAAdjustLibVars.cmake)
_MXA_ADJUST_LIB_VARS(EXPAT)
This will end up giving me the following variables:
EXPAT_LIBRARY /Toolkits/expat/lib/libexpat.dylib
EXPAT_LIBRARY_DEBUG /Toolkits/expat/lib/libexpat_debug.dylib
EXPAT_LIBRARY_RELEASE /Toolkits/expat/lib/libexpat.dylib
Is that more what you were after?
The source for these examples can be found at:
http://titanium.imts.us/viewvc/Task_7/MXADataModel/Resources/
Look for MXAFindExpat.cmake and MXAAdjustLibVars.cmake
Does that help your use case?

So I submitted a patch to add a new unset() command to CMake. The
command will unset normal or cache variables (causing them to
become undefined). The command also supports unsetting environment
variables, in case anyone has to do that.
The primary use case that drove me to implement this was this:
find_library(FOO_LIBRARY foo)
if(MSVC OR SEARCH_FOO_DEBUG)
find_library(FOO_LIBRARY_DEBUG food)
else()
unset(FOO_LIBRARY_DEBUG)
set(FOO_LIBRARY_DEBUG ${FOO_LIBRARY})
endif()
