Hi!, During ninja building occurred this error. It seems that webrtc-enumtypes.h is missing. Can you please help me to solve it?
ninja: error: 'subprojects/gst-plugins-bad/gst-libs/gst/webrtc/webrtc-enumtypes.h', needed by 'subprojects/gst-examples/webrtc/multiparty-sendrecv/gst/mp-webrtc-sendrecv.p/mp-webrtc-sendrecv.c.o', missing and no known rule to make it
