[CMake] Problem with CMAKE_SHARED_LIBRARY_SUFFIX on windows

[Ian.Appru at ubs.com]

Thanks for the hint - using SET_TARGET_PROPERTIES works as well
overriding 
CMAKE_SHARED_LIBRARY_SUFFIX and CMAKE_EXTRA_LINK_EXTENSIONS variables in
most cases.

The one exception I found being when an .xll suffixed library tries to
link the .lib 
file of another .xll library.

The release config build tries to link to MyExcelAddin.xll.lib

Using 
	SET(CMAKE_EXTRA_LINK_EXTENSIONS ".xll")
fixes the problem.

SET_TARGET_PROPERTIES probably needs a touch more attention.

See the SET_TARGET_PROPERTIES command.
You can set the prefix or postfix on a per target basis.
You should never change these variables.
