Maybe it would be sufficient to let the configure script print a summary
of features which would be included, and which not.
For example, if you forget to install the openSSL *headers* on a system
where openSSL is normally available then the NTP package will silently
be built without openSSL support, and when you use the resulting
binaries you wonder why things don't work as expected.
In a configure script for some other application I tried to build by
myself there was a summary line printed indicating which features would
be included, and which not, so I could see immediately that an optional
feature I was expecting was obviously missing, and could install the
required headers to have this optional feature supported.
In case of NTP under Linux at least the Linux capabilities, openSSL, and
PPS support come into my mind where a warning should be printed if these
features are not included simply because some header files have not been
installed on the build system.
