The build scripts included here are largely copies of the existing build scripts for Windows, so their usage is similar. The build products included here represent Blosc version 1.21.0 and OpenVDB 8.1.0, the same versions currently used on Windows. A subsequent change will update the module rules to put this new set of libraries into use with engine builds. #jira UE-153244 #rb none #preflight 628c1d8905113038b4af0d2c #fyi devon.penney [CL 20375476 by matt johnson in ue5-main branch]
