Undefined symbol. Module not loaded.

Hi! Thanks for creating so many great modules! I'm building OBS 27.0.1 on Ubuntu Studio 20.04 using the current git version for this module. I have made sure to remove all stale object files and cleaned the system of all previous install files. Besides the warnings about unused variables, obs-downstream-keyer seems to build cleanly. However, when I run OBS, there is a single error in the log file:

12:12:04 PM.972: os_dlopen(/usr//lib/obs-plugins/downstream-keyer.so->/usr//lib/obs-plugins/downstream-keyer.so): /usr//lib/obs-plugins/downstream-keyer.so: undefined symbol: _ZTI15DownstreamKeyer
12:12:04 PM.972:
12:12:04 PM.972: Module '/usr//lib/obs-plugins/downstream-keyer.so' not loaded

I'm a little out of my depth here, but I think it may have something to do with either compiler flags, the compiler version, or the libc I'm using. libc6 is 2.31, and gcc is 9.3.0.

I configured OBS using:

cmake -DUNIX_STRUCTURE=1 -DENABLE_PIPEWIRE=ON -DCMAKE_INSTALL_PREFIX=/usr -DBUILD_BROWSER=ON -DCEF_ROOT_DIR="/opt/cef_binary_4280_linux64" ..

Happy to provide any additional debugging and testing.

Some amount of refreshing the various plugin repos and clean builds seems to have resolved the issue, with no insight into what the issue was unfortunately. Closing.
