This issue was recently raised for the Linux environment. The problem is that
the readline library allows a choice of terminal libraries. Its build
instructions say this: "Readline uses the termcap functions, but does not link
with the termcap or curses library itself, allowing applications which link
with readline the to choose an appropriate library."

In many Linux distributions, the readline library is built so that it
automatically pulls in an appropriate library, so this is not an issue.
However, if the user installs readline from source (for example) it can be. I
added some words to the README file (for the next PCRE release) pointing out
that it may be necessary to specify LIBS=lncurses in these cases.

I know very little about CMake, and even less about Windows. I don't think I
should make that change unconditionally, however, for the reason given above.
After all, CMake does work on Linux as well as on Windows.

Does anybody else who sees this message have any ideas?
