%description
Wiimote is a Lab Streaming Layer (LSL) connector that pairs with a Nintendo
Wii Remote over Bluetooth (via wiiuse) and streams its button states and
accelerometer/IR motion data as LSL outlets, for synchronized recording
alongside other biosignal streams.

# Patch CMakeLists.txt:
#  1. Inject include(LSLCMake) after find_package(LSL) so installLSLApp() resolves
#     (LSLConfig.cmake does not touch CMAKE_MODULE_PATH).
#  2. De-vendor wiiuse: replace the network FetchContent clone (forbidden in
#     mock/COPR, and Fedora policy) with the system wiiuse-devel via find_library/
#     find_path; link ${WIIUSE_LIBRARY}; drop WIIUSE_STATIC (system lib is shared).

* Sat Jun 20 2026 Morgan Hough <morgan.hough@gmail.com> - 0.2.0-1.20230612git4cb2a42
- Initial RPM package for App-Wiimote (master commit 4cb2a42, the LSL Wii Remote
  connector). De-vendored the bundled FetchContent(wiiuse) to Fedora's
  wiiuse-devel (no network at build, per Fedora/COPR policy). Qt6 build; injects
  include(LSLCMake) so installLSLApp() resolves.
