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

%prep
%setup -q

# --- PATCHING ---
# 1. Remove internal library paths to force system linking
sed -i '/\$\$PWD\/external\/include/d' sigviewer.pro
sed -i '/\$\$PWD\/external\/lib/d' sigviewer.pro

# 2. Clean up existing hardcoded links in the .pro file
sed -i 's/-lbiosig//g' sigviewer.pro
sed -i 's/-lxdf//g' sigviewer.pro
sed -i 's/-llsl//g' sigviewer.pro

# 3. Manually link System Libraries
# We do NOT use PKGCONFIG here because your custom builds likely
# didn't generate .pc files for liblsl or libxdf.
# We explicitly link them, assuming they are in standard /usr/lib64.

echo "LIBS += -lbiosig -llsl -lxdf" >> sigviewer.pro

# Note: We do NOT add "PKGCONFIG += ..." lines for these.

%build
# We explicitly link against the system libraries here
# qmake-qt5 handles the Makefile generation
%qmake_qt5 \
    "INCLUDEPATH += %{_includedir}" \
    "LIBS += -L%{_libdir} -lxdf -lbiosig" \
