RFC: modular configuration in kdelibs

[Alexander Neundorf]

Hi,

I went through almost all configure checks in kdelibs/ConfigureChecks.cmake 
and annotated where the results are used, please have a look at the file.
There are a lot of checks whose results are only used in one directory: kdesu, 
kdecore and kjs mainly.
There are also a lot of checks whose results are used in kdecore and kio.
I put all configure checks whose results seem to be unused at the end of the 
ConfigureChecks.cmake.

I'd suggest:

1) to move all checks which are only used in one directory into this 
directory, either directly in the CMakeLists.txt there, or into e.g. 
kdecore/ConfigureChecks.cmake, or into e.g. ConfigureChecksKDECore.cmake
and have them create separate config headers in their subdirs: e.g. 
kdecore/config-kdecore.h (or kdecore/kdecore-config.h)

I did this already for the check for sys/soundcard.h which is only used in 
phonon.

2) keep all checks which are used in at least two subdirs in the toplevel 
ConfigureChecks.cmake.

3) what about the checks which are used in kdecore and kio ? They could be 
moved into the specialized cmake files and so appear twice. The results are 
cached by cmake, so they will be executed only once. Or keep them in the 
toplevel ConfigureChecks.cmake ?

4) remove the unused configure checks

What do you think ?

Bye
Alex
