From Luigi Calori, "when we link against something that comes out from a Find... we ususally have a variable <LINK_VAR_NAME>available like OPENTHREADS_LIBRARY,
so I' ve set up a macro that uses the variable name expanded for linking, and test if a variable ${LINK_VAR_NAME}_DEBUG
like OPENTHREADS_LIBRARY_DEBUG exists and in case uses it for linking in debug mode.
I' ve also set up FindOpenThreads to set up these variables.
I had to edit the core libraries CMakeLists to add the calls to the macros used.
I' ve tested under MSVC"
