these are really complex questions and I don´t think it could be solved
in one mail.
maybe there are also many possibilities to solve your problem and I´m
sure that I will not answer all.

Ok... first this question:
KDevelop´s project structure primarily leads on the directory structure
needed for automake/autoconf.
On the second hand there is created another subdirectory which has the
same name as the project, and this is KDevelop specific to simplify the
project handling (so "make" will be called from within this directory to
make only the stuff inside this directory (the "application" part of the
so the whole stuff was easier to handle in the KDevelop 1.x project
But returning to the question:
_Only_ Makefile.ams and configure.in will be patched by KDevelop.
If you want to setup own flags this should be done in one of these file
(either by KDevelop usage or manually depending on the problem you
If you would change something in them, so you have to invoke certain
applications to get the "real" Makefiles (these tools are automatically
called by invoking "make Makefile.dist" or using KDevelop´s command
[Build/Automake and autoconf] and by the "configure"-call):
Here a very very simply explaination of these tools:
this creates from configure.in, acinclude.m4 and system specific *.m4
files an aclocal.m4 - a little bit like linking them together.
(aclocal.m4 then is necessary for the next tool-binaries)
for your problem a secondary call. This tries to make a CONFIG_HEADER
template... if there is a AC_CONFIG_HEADER-call inside configure.in...
Normally this is a AC_CONFIG_HEADER(config.h) call, so something like:
cat config.h.top acconfig.h (+ AC_(UN)DEFINE* calls inside aclocal.m4
and configure.in) config.h.bot > config.h.in
will be done.
this scans the project directory structure and makes for each
Makefile.am a platform independable Makefile.in.
The directories which have to be scanned are taken from configure.in
(see AC_OUTPUT macro call)
4) perl am_edit:
this "magic" call patches the Makefile.in´s for QT/KDE applications
(this has moc-support, po-support, some workarounds for automake bugs,
BTW: this call substitutes "automoc".
this call makes a configure-script from configure.in and aclocal.m4
then at the end
this call converts Makefile.in´s and the config.h.in (if present) to
platform dependent Makefiles and config.h.
So you can see, the only thing KDevelop makes is to patch
Makefile.am/configure.in (and you should also do so)...
the rest will be created by automake/autoconf stuff.

I will answer these questions in another mail, because I still have to
Ok... KDevelop lacked for creation and usage of shared lib.
But I've done a maybe minimalistic, but as I hope a sofisticated, shared
library implementation, more about that in the next mail ;-).
