You can check the dependencies of readline with this command:
$ ldd /path/to/libreadline.so

The undefined symbols in this library can be checked with:
$ nm -u /path/to/libreadline.so

In Linux, the usual required library is "libncurses". Then, you need the 
"libncurses-devel" package. Some systems prefer other library.

To link the transitive dependency, add some arguments to CMake. For instance:
$ cmake \
        -DCMAKE_EXE_LINKER_FLAGS=-lncurses \
        -DCMAKE_SHARED_LINKER_FLAGS=-lncurses \
        ...

That would be the same as defining the environment variable: LDFLAGS=-lncurses
