Viskores-GRAPH

Library implementing a Viskores node-graph abstraction with support for ANARI mappers.

Build + install

Building Viskores-GRAPH requires the following:

• CMake 3.17+
• C++17 compiler
• Viskores 1.0
• ANARI-SDK 0.14.0+

Viskores and ANARI-SDK can be found via placing their installation locations on CMAKE_PREFIX_PATH.

The single libviskores_graph will install to ${CMAKE_INSTALL_PREFIX}/lib, and is usable with any Viskores/ANARI app if either it is installed to the same location as the ANARI-SDK or libviskores_graph is placed on LD_LIBRARY_PATH respectively.

Viskores-GRAPH is currently only tested on Linux, but Windows support is planned.

Using the superbuild

You can build ANARI-SDK, Viskores, and Viskores-GRAPH all in a single build directory using the superbuild found in scripts/superbuild. Simply run a standard CMake config + build using that CMakeLists.txt and all three projects will be installed to CMAKE_INSTALL_PREFIX. Note that the superbuild is a separate entity to building Viskores-GRAPH by hand using the CMakeLists.txt found in the root source directory.

Using Viskores-GRAPH from an install with CMake

Viskores-GRAPH installs exports a CMake target for the main library: viskores_graph::viskores_graph. This target is found with CMake via find_package(viskores_graph) in the downstream project.

When the package is found, it will look for Viskores + ANARI to ensure those dependencies are present. Use CMAKE_PREFIX_PATH to point them just like when building Viskores-GRAPH itself.
