Sergey Sharybin 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.

Information on how to build OpenSubdiv
----
Overview
========
Assuming that you have `cloned <getting_started.html>`__ the source repository
and selected an appropriate release branch, the following instructions will
walk you through the Cmake and configuration and build process.
Cmake is a cross-platform, open-source build system. Cmake controls the compilation
process using platform independent configuration files in order to generate
makefiles and workspaces that are native to the platform of choice.
The process involves the following steps:
1. Locate & build the requisite dependencies
2. Configure & run CMake to generate Makefiles / MSVC solution / XCode project
3. Run the build from make / MSVC / XCode
----
Step 1: Dependencies
====================
Cmake will adapt the build based on which dependencies have been successfully
discovered and will disable certain features and code examples accordingly.
Please refer to the documentation of each of the dependency packages for specific
build and installation instructions.
Required
________
- `cmake <http://www.cmake.org/>`__ version 2.8
Optional
________
- `Ptex <http://ptex.us/>`__ (support features for ptex textures and the
ptexViewer example)
- `Zlib <http://www.zlib.net/>`__ (required for Ptex under Windows)
- `GLEW <http://glew.sourceforge.net/>`__
- `CUDA <http://www.nvidia.com/object/cuda_home_new.html>`__
- `TBB <http://www.threadingbuildingblocks.org/>`__
- `OpenCL <http://www.khronos.org/opencl/>`__
- `DX11 SDK <http://www.microsoft.com/>`__
- `GLFW <https://github.com/glfw/glfw>`__ (required for standalone examples
and some regression tests)
- `Docutils <http://docutils.sourceforge.net/>`__ (required for reST-based documentation)
- `Python Pygments <http://www.pygments.org/>`__ (required for Docutils reST styling)
- `Doxygen <www.doxygen.org/>`__
----
Step 2: Configuring CMake
=========================
One way to configure CMake is to use the `CMake GUI <http://www.cmake.org/cmake/help/runningcmake.html>`__.
In many cases CMake can fall back on default standard paths in order to find the
packages that OpenSubdiv depends on. For non-standard installations however, a
complete set of override variables is available. The following sub-section lists
some of these variables. For more specific details, please consult the source of
the custom CMake modules in the OpenSubdiv/cmake/ folder.
Useful Build Options
____________________
The following configuration arguments can be passed to the cmake command line.
.. code:: c++
-DCMAKE_BUILD_TYPE=[Debug|Release]
-DCMAKE_INSTALL_PREFIX=[base path to install OpenSubdiv (default: Current directory)]
-DCMAKE_LIBDIR_BASE=[library directory basename (default: lib)]

-DMAYA_LOCATION=[path to Maya]
-DTBB_LOCATION=[path to Intel's TBB]
-DICC_LOCATION=[path to Intel's C++ Studio XE]
-DNO_LIB=1 // disable the opensubdiv libs build (caveat emptor)
-DNO_EXAMPLES=1 // disable examples build
-DNO_REGRESSION=1 // disable regression tests build
-DNO_PYTHON=1 // disable Python SWIG build

Environment Variables
_____________________
The paths to Maya, Ptex, GLFW, and GLEW can also be specified through the
following environment variables:
.. code:: c++
MAYA_LOCATION
PTEX_LOCATION
GLFW_LOCATION
GLEW_LOCATION
Automated Script
________________
The GUI solution will probably become a burden for active developpers who tend to
re-run the configuration step fairly often. A scripted solution can save a lot of
time. Here is a typical workflow:
.. code:: c++
git clone https://github.com/PixarAnimationStudios/OpenSubdiv.git <folder>
cd <folder>
mkdir build
cd build
source ../../cmake_setup
Where *cmake_setup* is a configuration script.
Here is an example CMake configuration script for a full typical windows-based
build that can be run in GitShell :
.. code:: c++
#/bin/tcsh
# Replace the ".." with a full path to the root of the OpenSubdiv source tree if necessary
"c:/Program Files (x86)/CMake 2.8/bin/cmake.exe" \
-G "Visual Studio 10 Win64" \
-D "GLEW_LOCATION:string=c:/Program Files/glew-1.9.0" \
-D "GLFW_LOCATION:string=c:/Program Files/glfw-2.7.7.bin.WIN64" \
-D "OPENCL_INCLUDE_DIRS:string=c:/ProgramData/NVIDIA Corporation/NVIDIA GPU Computing SDK 4.2/OpenCL/common/inc" \
-D "_OPENCL_CPP_INCLUDE_DIRS:string=c:/ProgramData/NVIDIA Corporation/NVIDIA GPU Computing SDK 4.2/OpenCL/common/inc" \
-D "OPENCL_LIBRARIES:string=c:/ProgramData/NVIDIA Corporation/NVIDIA GPU Computing SDK 4.2/OpenCL/common/lib/x64/OpenCL.lib" \
-D "MAYA_LOCATION:string=c:/Program Files/Autodesk/Maya2013.5" \
-D "PTEX_LOCATION:string=c:/Users/opensubdiv/demo/src/ptex/x64" \
..
# copy Ptex dependencies (Windows only)
mkdir -p bin/{Debug,Release}
\cp -f c:/Users/opensubdiv/demo/src/zlib-1.2.7/contrib/vstudio/vc10/x64/ZlibDllRelease/zlibwapi.dll bin/Debug/
\cp -f c:/Users/opensubdiv/demo/src/zlib-1.2.7/contrib/vstudio/vc10/x64/ZlibDllRelease/zlibwapi.dll bin/Release/
\cp -f c:/Users/opensubdiv/demo/src/ptex/x64/lib/Ptex.dll bin/Debug/
\cp -f c:/Users/opensubdiv/demo/src/ptex/x64/lib/Ptex.dll bin/Release/
.. container:: impnotip
* **Important**
Notice that the following scripts start by **recursively removing** the *../build/* and
*../inst/* directories. Make sure you modify them to suit your build workflow.
Here is a similar script for \*Nix-based platforms:
.. code:: c++
echo "*** Removing build"
cd ..; rm -rf build/ inst/; mkdir build; cd build;
echo "*** Running cmake"
cmake -DPTEX_LOCATION=/home/opensubdiv/dev/opensource/ptex/install \
-DGLEW_LOCATION=/home/opensubdiv/dev/opensource/glew/glew-1.9.0 \
-DGLFW_LOCATION=/home/opensubdiv/dev/opensource/glfw/build \
-DDOXYGEN_EXECUTABLE=/home/opensubdiv/dev/opensource/doxygen/inst/bin/doxygen \
-DCMAKE_INSTALL_PREFIX=../inst \
-DCMAKE_BUILD_TYPE=Debug \
..
Here is a similar script for OSX:
.. code:: c++
echo "*** Removing build"
cd ..; rm -rf build/ inst/; mkdir build; cd build;
echo "*** Running cmake"
cmake -DOPENGL_INCLUDE_DIR=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/System/Library/Frameworks/OpenGL.framework/Headers \
-DGLFW_LOCATION=/Users/opensubdiv/dev/opensource/glfw/inst \
-DNO_OMP=1 -DNO_REGRESSION=0 \
-DCMAKE_INSTALL_PREFIX=../inst \
-DCMAKE_BUILD_TYPE=Debug \
.."
Using Intel's C++ Studio XE
___________________________
OpenSubdiv can be also be built with `Intel's C++ compiler <http://software.intel.com/en-us/intel-compilers>`__
(icc). The default compiler can be overriden in CMake with the following configuration options:
.. code:: c++
-DCMAKE_CXX_COMPILER=[path to icc executable]
-DCMAKE_C_COMPILER=[path to icc executable]
The installation location of the C++ Studio XE can be overriden with:
.. code:: c++
-DICC_LOCATION=[path to Intel's C++ Studio XE]
Using Clang
___________
CMake can also be overriden to use the `clang <http://clang.llvm.org/>`__ compilers by configuring the following options:
.. code:: c++
-DCMAKE_CXX_COMPILER=clang++ \
-DCMAKE_C_COMPILER=clang \
----
Step 3: Building
================
CMake provides a cross-platform command-line build:
.. code:: c++
cmake --build . --target install --config Release
Alternatively, you can native toolkits to launch the build. The steps differ for each OS:
* *Windows* :
launch VC++ with the solution generated by cmake in your build directory.
* *OSX* :
run *make* in the build directory
* *\*Nix* :
| run *make* in your build directory
| - use the *clean* target to remove previous build results
| - use *VERBOSE=1* for verbose build output
.. container:: notebox
**Note**
We recommend against using CMake's Xcode project generator (-G "Xcode") on OSX, as it seems to
generate some dependencies incorrectly. We recommend instead reverting to Makefiles on OSX, and
launching *make*, instead of *xcodebuild* to execute the build (make sure to install the command
line tools in Xcode)
----
Build Targets
_____________
Makefile-based builds allow the use of named target. Here are some of the more
useful target names:
*osd_\<static\|dynamic\>_\<CPU\|GPU\>*
| The core components of the OpenSubdiv libraries
|
*\<example_name\>*
| Builds specific code examples by name (glViewer, ptexViewer...)
|
*doc*
| Builds ReST and doxygen documentation
|
*doc_html*
| Builds ReST documentation
|
*doc_doxy*
| Builds Doxygen documentation
