Hi,
as the LyX Chat patch would add a new dependency on libqxmpp, is it better to
add some autoconf logic that excludes it at compile-time, if said libraries
are not found on the system ?
Hints in this regard ?
Have a look at what is done in config/spell.m4 for the different spell
checkers, There are two ingredients:
- a USE_xxx #define, that can be used in the code to do conditional
compilation
- a USE_xxx automake conditional that is used to decide which pieces of
code shall be compiled.
