This sample requires a development package (or locally-built) LLVM library
between versions 7 to 14 inclusive. LLVM 15 defaults to using opaque pointers,
which are currently not supported in libNVVM.
which are not supported in libNVVM for pre-Blackwell architectures.
The LLVM_HOME environment variable is required for users who wish to build the
