Craig,
I'm not at all an expert in cmake - somebody else did the necessary work
to allow PCRE to use it - but I will make a stab at answering your
questions. Yes, the users who want to build using cmake do have to
install cmake (at least on Linux, so I assume also for Windows).

There's a parallel structure. By imitation, I have updated it from time
to time to add stuff, but I'm not knowledgeable about the full rules.
See CMakeLists.txt in a PCRE distribution. There are some supporting
files in cmake/ and also cmake_install.cmake and config-cmake.h.in.
