The location of the shaders changed with OSL 1.11.10. This commit is therefore in addition to D10212. @sybren With the latest SVN libraries, I am fairly certain there is a "OSL not found" in the CMake output. Can you check on Linux? @LazyDodo Since you haven't pushed the new OSL libs yet, this should not be a problem on Windows. So this will only be needed whenever those land.
