The new build system uses CMake (http://www.cmake.org). It handles
all platform differences.

In addition to the information in the README.md file on prerequisites, here
are some additional guidelines:

The XDR functions are no longer in the GNU library, so you will need an
additional package to supply them. The README.md suggests one; another is
tirpc. This is available on OpenSUSE, for example, via
zypper install libtirpc-devel.

The documentation can only be built if you have latex2html (version
2008), pdflatex and lyx installed. If you don't, turn off the
ENABLE_HELP option (using the ccmake command or any other CMake
frontend).

Note that the GUI version definitely needs FLTK-1.3. CMake apparently finds
a system-installed version of this without difficulty. However, it is not
entirely clear if static linking, should you prefer it, will work properly
with the current setup. One possibility is to build FLTK yourself and ensure
that your own version is found before the system one; that should allow static
linking.

For the console version you will have to make sure your system
offers a SYSV compatible curses.  You can check that you do by looking
at its include file curses.h; it should e.g. contain KEY_ macros.  If you
have a system which contains BSD and SYSV curses libraries, make sure (by
checking the cmake variables) that the SYSV curses.h is used.  This
particularly applies if you use the SYSV curses clone ncurses.  If you do
so, further make sure that you use version 4 or higher.  Otherwise teapot
may not work correctly and you get corrupted screen output.  Since version
4 makes it easy to be built as shared (ELF) library, this can reduce the
size of the teapot binary considerably.

If you want the curses frontend to be fully UTF-8 aware, you need
libncursesw (Debian package name: libncursesw5-dev).
