I'm not familiar with cmake. How is it checking whether or not a
particular function exists in a library, and why does it need to know?

Well, other than the autoconf-style compile-a-program-and-see-if-it-links
strategy, there is always `nm':
caleb:readline-6.3-patched chet$ nm libreadline.a | grep
rl_filename_completion_function
00000000000015f0 T _rl_filename_completion_function
Note that some systems preface global symbols with a `_'.
