I removed the flag --no-undefined and it was compiled and worked like a charm. I needed the flag to spot the linker errors for linking with the external *libseal.a* library.
As for my other question regarding the unused linker path *-L"/usr/local/lib"*. I'm using Fedora 28 (RedHat) and in this distribution the default path for libs is /usr/lib64, so I can use this setting or change it to include the */usr/local/lib* path as well.
