Hello,
as I never tried cmake before, I gave it a try today. It works fine,
except it doesn't correctly detect readline in my case.
The library is detected (and it works, as I used it before with make), but
the rl_filename_completion_function detection doesn't work :
-- Found READLINE: /lib/libreadline.so
-- Looking for rl_filename_completion_function
-- Looking for rl_filename_completion_function - not found
in CMakeError.log :
Determining if the function rl_filename_completion_function exists failed
with the following output:

I have the feeling that unless with X11 for example where -lX11 is added,
here we don't have -lreadline added to gcc, which would explain why ldd is
exiting with an error.
In the end HAVE_READLINE is not defined in config.h
Thomas, do you have an idea (or maybe others encountered this too) ?
