I compile the software on my system 100% on my own, so I run
./configure --help on everything and can scan the output very fast.
Autoconf defines internally the meaning of --with-PACKAGE and
--without-PACKAGE, and --enable-FEATURE / --disable-FEATURE. You
could assume, that the one invoking ./configure is aware of the
principles, and mention only on of --with-X / --without-X (merely, the
one which is not default and which is not auto-detected).
The final summary is indeed great, but in order to adjust the right
options, with the current "./configure --help" output, I need first to
run "./configure" then analyze the summary, and then tweak options to
activate more features. Otherwise I have to either put preventively
unnecessary much --enable/--with parameters, or to run "./configure",
see what is missing, adjust the parameters and then run again
"./configure". The purpose of the proper output of "./configure
--help" I see in abolishin the need to run "./configure" twice, for
the above mentioned reasons.
Comparing the possible options, and the summary, I see that there is
no output for the symbol-hiding; versioned symbols; compiler
optimizations; coocies; list of protocols, which are supported by
curl, but which will not be compiled in. In these particular cases,
the summary is not sufficient.
The further, I cannot find documentation how the --enable-optimize
option works, neither by running ./configure nor by looking in
