./configure --help
+If you want to use dynamic shared libraries automake, autoconf
+(aka GNU autotools) and libtool must be available. The DHCP
+distribution provides 3 configure.ac* files: the -lt version
+has no libtool support and was copied to the configure.ac
+standard file in the distribution. To enable libtool support
+you should perform these steps:
+
+ cp configure.ac+lt configure.ac
+ autoreconf -i
+
+after you can use the regenerated configure as usual
+(with libtool support (--enable-libtool) on by default):
+
+ ./configure
+
+For compatibility (and people who don't read this documentation)
+the --enable-libtool configuration file is supported even by
+the distributed configure (and off by default). The previous
+steps are performed and the regenerated configure called with
+almost the same parameters (this "almost" makes the use of
+this feature not recommended).

DYNAMIC DNS UPDATES
A fully-featured implementation of dynamic DNS updates is included in
arguments.
[ISC-Bugs #39318]
+- Added support of dynamic shared libraries with libtool. A new
+ --enable-libtool configuration parameter is available but
+ should not be used directly: *please* read the build configuration
+ section in the README file for the recommended procedure.
