%description
SigViewer is a powerful viewing and scoring application for biosignals.
It supports various data formats including XDF, GDF, EDF, BDF.

# check by writing the file directly with the expected version strings.

%changelog

* Tue May 26 2026 Morgan Hough <morgan.hough@gmail.com> - 0.7.1-5
- Strip apostrophes from %%install comments. The %%cmake_install
  macro emits a line-continuation; bash then treats apostrophes
  in following comment lines as quote-starts that consume the
  rest of the fallback block as one literal argument to cmake.
- Add a no-op : before the fallback to terminate any leftover
  line-continuation from the macro expansion.

* Tue May 26 2026 Morgan Hough <morgan.hough@gmail.com> - 0.7.1-4
- Add binary-find fallback after %%cmake_install: upstream's
  CMakeLists.txt may lack install(TARGETS sigviewer ...), in which
  case the binary stays in the build tree. Locate and install it
  manually if cmake_install didn't place it at %{_bindir}/sigviewer.
* Sat May 23 2026 Morgan Hough <morgan.hough@gmail.com> - 0.7.1-3
- Require biosig4c++-devel >= 3.9.4 (now in COPR); both pinned external deps
  are at the exact versions upstream expects, so the stub versions.cmake
  matches reality.

* Sat May 23 2026 Morgan Hough <morgan.hough@gmail.com> - 0.7.1-2
- Port spec from qmake/Qt5 to cmake/Qt6 (upstream 0.7.1 dropped qmake).
- Stub external/versions.cmake to satisfy upstream's pinned-version FATAL_ERROR
  (LIBXDF 0.99.10 is exact from COPR; LIBBIOSIG 3.9.4 vs system 2.6.1 — will
  iterate if biosig 2.x API isn't compatible with sigviewer 0.7.1 needs).
- Repoint upstream's STATIC IMPORTED dep targets at system shared libs.

* Thu Apr 23 2026 Morgan Hough <morgan.hough@gmail.com> - 0.7.1-1
- Update to 0.7.1

* Wed Jan 07 2026 Your Name <your.email@example.com> - 0.6.4-1
- Initial package for Fedora
- Switched to QMake build system
- Patched to link against system libxdf and biosig4c++
