I want run cog with WPEBackend-rdk，and weston to see web pag. I compile WPEBackend-rdk with cmake and make command，and I have libWPEBackend-default.so link to libWPEBackend-rdk.so. When I run cog，it got eroor
Here is my comile commands:
cmake .. -DCMAKE_EXPORT_COMPILE_COMMANDS=Yes -DCMAKE_BUILD_TYPE=Debug -DBACKEND_WAYLAND_EGL=1 -DCMAKE_INSTALL_PREFIX=/xxx/wpe/install
make -j12 install
And，here is the cog command output：

$ cog "www.youtube.com/tv"

My issue was resolved by switching to rdk.
