You can run with "make VERBOSE=1" then you'll see the exact command that
make is using for linking.

Anyway, this can have one of the two reasons. Either the linker thinks
that "-lregex" is a file, and cannot find it (unlikely, but possible,
depends on what else is on the command line).

Or it simply cannot find the library - libregex.so (or libregex.a).
You need to specify a path to the library with the linker flag
-L/path/to/the/library
