I tried to use debug info and run my applications, CLion project(which
contains my Gstreamer code on C) output this:
/usr/bin/cli: symbol lookup error:
/home/user/MonoDevelopProjects/GTKSharpGstDllCaller/GTKSharpGstDllCaller/bin/Release/libgstTestDLL.so:
undefined symbol: gst_video_overlay_get_type
