6ef232c95a Integrate CLEW into osd library and examples
If the system has CLEW installed (which is detected by recently
added FindCLEW routines) then OpenSubduv would be compiled against
this library.

It makes binaries and libraries more portable across the systems,
so it's possible to run the same binary on systems with and without
OpenCL SDK installed.

The most annoying part of the change is updating examples to load
OpenCL libraries, but ideally code around controllers and interface
creation is to be de-duplicated anyway.

Based on the pull request #303 from Martijn Berger

05a7db5e14 Make CMake path variables more robust
Add quotes around variables containing paths - this might require a second pass...

8918173fda Improve stringification of shaders & kernels in build.
- added a _stringify function to top CMakeLists
- switched all stringification tasks to use the macro
- all suffixes are now .gen.h instead of .inc (to help cmake track dependencies)

00b0d95058 Remove CMake compiling redundancies
- set OBJECT targets for osd cpu & gpu libs, and use the obj target for
  static and dynamic linking

- add a new examples_common_obj OBJECT target
- replace direct source dependencies to obj target in all examples CMakeLists

This change makes it possible to not re-compile the same source files
multiple times when they are used in multiple targets. Thanks to jcowles
for uncovering the CMake functionality.

Note: it seems that multi-process build is working again (gmake -j <x>)

f7f2ca2581 Move uniform block definitions out of osd common shader into client shader.
Important notice: all client shader code must have following functions and compose them to osd intrinsic shaders (vertex/tessEval/tessControl)

mat4 OsdModelViewMatrix()
mat4 OsdProjectionMatrix()
mat4 OsdModelViewProjectionMatrix()
float OsdTessLevel()
int OsdGreogryQuadOffsetBase()
int OsdPrimitiveIdBase()

We probably should write a utility class for basic binding of them, to make client code simpler.

791995cf32 Refactoring Ptex Mipmap and Analytic Displacement code
Moving Takahito's implementation into the core API:
- added <gl/d3d11>PtexCommon.<glsl/hlsl> shader code
- added control to enable Ptex common trunk in <gl/d3d11>DrawRegistryBase classes
- fixed GL & D3D11 ptexViewer examples to use the new API
