** CMake file created to build OpenCV
 +
** Enabling the ITK OpenCV Bridge:
 +
*** The Slicer version of ITK needed changes from this patch in order to be able to build with the module enabled: [https://github.com/InsightSoftwareConsortium/ITK/commit/412dd83a680cc024c12f971ec57f76881c7eab78 COMP: simplify ITKVideoBridgeOpenCV dependency]
 +
*** Building the bridge outside of the source referred to ITK mailing list posts:
 +
**** [http://itk-users.7.n7.nabble.com/Problems-building-ITK-Snap-outside-the-Insight-Applications-tree-td14733.html Building ITK SNAP outside of the application]
 +
**** New post: [http://public.kitware.com/pipermail/community/2015-December/010521.html Building BridgeOpenCV outside of ITK]
 +
*** Consulted with Jim on best practices for building ITK and linking to libs and include dirs
 +
*** Worked with JC to craft CMake files to build the bridge
 +
**** Pointed to relevant blog post: [http://www.kitware.com/blog/home/post/997 Build ITK Modules Outside the Main Repository]
 +
*** Matt McCormick proposed a patch to ITK to enable building the bridge outside of ITK: [http://review.source.kitware.com/#/c/20633/3 Allow ITKVideoBridgeOpenCV to be built externally.]
 +
*** Extension topic branch builds against the ITK trunk version of the bridge with Matt's patch, and loads into Slicer: [https://github.com/naucoin/SlicerOpenCV/tree/Enable-ITK-BridgeOpenCV Enable-ITK-BridgeOpenCV]
 +
*** To do:
 +
**** patch Slicer's branch of ITK
 +
**** set up dependency with the digital pathology module so that it uses this version of OpenCV
