Current Behavior: Running the command:

quantum-opt --version

Currently, return:

LLVM (http://llvm.org/):
  LLVM version 19.0.0git
  Optimized build with assertions.

It only displays the LLVM version.

Expected Behavior: It should also display the Catalyst version alongside the LLVM version. For example:

For example:

Catalyst version 0.10.0
LLVM (http://llvm.org/):
  LLVM version 19.0.0git
  Optimized build with assertions.

Proposed Solution:

• Update the version printer in mlir/tools/quantum-opt/quantum-opt.cpp to include the Catalyst version.
• Use the llvm::cl::AddExtraVersionPrinter function, as documented here: AddExtraVersionPrinter

Notes:

• The Catalyst version is defined in frontend/catalyst/_version.py.
• The version string should be retrieved from there. If that’s not feasible in C++, an alternative such as pulling the version from the Git metadata or generating it at build time would be great.
