Note that because the engine already embeds its own version(s) of LZ4 which is bundled with Blosc, we apply a patch to the Blosc source that prepends a prefix to all of the non-static and non-inlined functions in Blosc's embedded version of LZ4. This ensures that the LZ4 symbols introduced by Blosc do not collide with those in the engine when building monolithically. A subsequent change will activate this new version of Blosc and include a rebuild of OpenVDB which uses it, followed by another change that removes the old build products for version 1.5.0. #jira UE-139647 #rb josh.adams #preflight 627978609c764d1f1e7c11c2 [CL 20127234 by matt johnson in ue5-main branch]
