I have some more information on this.

For regular object file builds you have a makefile rule that looks like 
this:

Model/CMakeFiles/Manta_Model.dir/Backgrounds/ConstantBackground.o: 
/tmp/bigler/manta/trunk/src/Model/Backgrounds/ConstantBackground.cc
	$(CMAKE_COMMAND) -E cmake_progress_report 
/tmp/bigler/manta/trunk/opt/CMakeFiles $(CMAKE_PROGRESS_3)
	@$(CMAKE_COMMAND) -E cmake_echo_color --switch=$(COLOR) --green 
"Building CXX object 
Model/CMakeFiles/Manta_Model.dir/Backgrounds/ConstantBackground.o"
	/usr/bin/g++-4.0   $(CXX_FLAGS) -o 
Model/CMakeFiles/Manta_Model.dir/Backgrounds/ConstantBackground.o -c 
/tmp/bigler/manta/trunk/src/Model/Backgrounds/ConstantBackground.cc




For the library you invoke the cmake program with the link.txt file:

lib/libManta_Model.so: Model/CMakeFiles/Manta_Model.dir/build.make
	@$(CMAKE_COMMAND) -E cmake_echo_color --switch=$(COLOR) --red --bold 
"Linking CXX shared library ../lib/libManta_Model.so"
	cd /tmp/bigler/manta/trunk/opt/Model && $(CMAKE_COMMAND) -P 
CMakeFiles/Manta_Model.dir/cmake_clean_target.cmake
	cd /tmp/bigler/manta/trunk/opt/Model && $(CMAKE_COMMAND) -E 
cmake_link_script CMakeFiles/Manta_Model.dir/link.txt --verbose=$(VERBOSE)



In 2.2.3 you invoke the linking directly:

lib/libManta_Model.so: Model/CMakeFiles/Manta_Model.dir/build.make
	@echo "Linking CXX shared library ../lib/libManta_Model.so"
	$(CMAKE_COMMAND) -E remove -f ../lib/libManta_Model.a 
../lib/libManta_Model.so
	cd /home/sci/bigler/manta/trunk/opt-4.0.2/Model && /usr/bin/g++-4.0 
-fPIC -Wl,-rpath,/usr/lib/gcc/i586-suse-linux/4.0.2 -shared 
-Wl,-soname,libManta_Model.so -o ../lib/libManta_Model.so 
$(Manta_Model_OBJECTS) $(Manta_Model_EXTERNAL_OBJECTS) 
-L/home/sci/bigler/manta/trunk/opt-4.0.2/lib 
-L/home/sci/bigler/pub/src/teem/muzzle-opt/bin -lManta_Image 
-lManta_Interface -lManta_Core -lteem -lpng -lSCIRun_Core 
-Wl,-rpath,/home/sci/bigler/manta/trunk/opt-4.0.2/lib:/home/sci/bigler/pub/src/teem/muzzle-opt/bin 




The object file build calls the compiler directly and the library 
linkage calls the cmake program with the $(VERBOSE) variable.  My guess 
is that calling "make -s" doesn't override the VERBOSE variable.

I liked being able to turn on verbose makefiles and making them silent 
by invocation.  This allowed me to rerun the make build with out the 
silent option when it needed it without having to reconfigure and 
rebuild the world.

Anyone have ideas of how to get around this?

Thanks,
James
