I'm trying to build a C++ project on my Fedora 31 VM, but it's returning an error with regards to ld:
/usr/bin/ld: /usr/local/lib/libglog.so: undefined reference to symbol '_ZN6google14FlagRegistererC1IbEEPKcS3_S3_PT_S5_'
/usr/bin/ld: /usr/lib64/libgflags.so.2.2: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
make[2]: *** [proxy_ws/CMakeFiles/proxy_lws.dir/build.make:225: proxy_ws/proxy_lws] Error 1
make[1]: *** [CMakeFiles/Makefile2:1117: proxy_ws/CMakeFiles/proxy_lws.dir/all] Error 2
make: *** [Makefile:150: all] Error 2
It's referring to a problem with libgflags, so I ran ld -lgflags --verbose and got:

How can I fix this?
