%description
XDFStreamer is a small Qt application that replays signals stored in an XDF
file as Lab Streaming Layer (LSL) streams.  It is useful for prototyping and
debugging downstream LSL clients without re-running the original experiment.

%changelog
* Mon Jun 02 2026 Morgan Hough <morgan.hough@gmail.com> - 1.14.0-1.20260602gitd718398
- Initial RPM package for App-XDFStreamer (master commit d718398).
- Inject include(LSLCMake) after find_package(LSL) for installLSLApp().
- Replace find_package(libxdf) with direct find_library/find_path because
  the COPR libxdf does not yet ship cmake config files.
