From Stephan Huber, "the softshadowmap-implementation does not compile on os x, to be more
...
precise, the shader does not compile on os x because of some
type-conflicts ala "can not convert from const int to const float"
So I changed the offending lines to force the type of the vars. It works
now on OS X (albeit very slowly, 3fps on a 7300), perhaps you find the
changes useful. Note: perhaps there is a better way in shaders to
cast/convert from int to float and viceversa."

From Bruno Hebelin,

"I have adapted to osgShadow the soft shadow map technique described in "Efficient Soft-Edged Shadows Using Pixel Shader Branching" by Yury Uralsky, Chapter 17 of GPU Gems 2 (Matt Pharr ed. Addison-Wesley).
Here is my code in attachment: basically, it works in the same way as osgShadow/ShadowMap (core code is copied from it) but implements a specific GLSL shader for the soft rendering of penumbra.
I have tested it under Linux with a NVidia graphic card, but there should be no dependency on platform nor on the graphics driver (as far as they support GLSL 2). Screenshots attached show the current results (frame rate bound to v-sync, but the shader takes actually not much time)."

of these are public APIs and therefore will break linkage to existing

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"
