It ends with:[ 60%] Linking C shared library libslope.dll C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/9.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: CMakeFiles/slope.dir/objects.a(chart.c.obj):chart.c:(.text+0x11): undefined reference to `g_type_class_peek_parent' C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/9.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: CMakeFiles/slope.dir/objects.a(chart.c.obj):chart.c:(.text+0x32): undefined reference...

Just noticed the same problem. It used to work. PS I hate .webp!
