BLT

Build, Link, and Test

BLT is a composition of CMake macros and several widely used open source tools assembled to simplify HPC software development.

BLT was released by Lawrence Livermore National Laboratory (LLNL) under a BSD-style open source license. It is developed on github under LLNL’s github organization: https://github.com/llnl/blt

Note

BLT officially supports CMake 3.8 and above. However we only print a warning if you are below this version. Some features in earlier versions may or may not work. Use at your own risk.
