### Configuring SCIRun with Prebuilt OSPRay

To use the OsprayViewer module with a prebuilt binary, you need to download from the [releases page](https://github.com/ospray/OSPRay/releases) and extract the zip. Only OSPRay 2.4 and 2.10 have been tested. Then add the directory to your shell's PATH variable. CMake will automatically find it when the flag `PREBUILT_OSPRAY` is enabled.

## Tagging Releases
On an OSX system, run script `release.sh` in the `src` directory with the release name in format ***beta.XX*** as a parameter.
