Hi,

as I don't really know how feasible / desireable this is, I'm posting to this 
list instead of opening a feature request right away.

The problem:
The KDE-build system does about everything you might ever want from a build 
system. In fact, it may do a little more. I suppose, when building the main 
KDE-sources, all the various checks in ./configure serve a purpose.
However, the KDE-build system (the admin dir) is also used for various third 
party KDE-application. KDevelop uses the KDE-build system for new projects. 
For such projects, all the test in ./configure are generally overkill.
In my projects, the size of the configure script is close to reaching 1MB. It 
takes quite a while to complete even on relatively new machines. For many 
tests I can tell quite definitely that I simply don't need them. In fact, for 
some I can tell that most projects could care less about the result of those 
tests.
On some problematic hosts (e.g. some compile farm servers on sourceforge), I 
even had to manually remove parts of the configure-script to get past the 
configure stage - removing parts that I really did not need, by the way.
Still it simply does not sound like a good idea to modify the copies of the 
files in the admin-dir in my projects. After all, I want to update those 
files every once in a while to keep track of recent changes/fixes.

What I think would be cool:
It would be nice to have some simple file which allows you to specify some 
configure tests that should not be conducted. In my vision, there'd be one 
option for each "checking if"-line ./configure prints out (or at least for 
some less important ones). Something like:

check_g77 = false
check_mcopidl = false
check_uic = false
check_moc = true
...

Again, I don't know whether this is feasible at all (or if something like this 
is already doable), so please bear with me. Still, something like this would 
be _very_ nice.

Thomas
