checks for zlib, perl and carbon in non-kdelibs modules ?

[Alexander Neundorf]

Hi,

currently all top-level CMakeLists.txt in the KDE modules in check for zlib, 
perl and (on OS X) carbon.
Are these required ?

For kdelibs (and so basically for all the rest of KDE) zlib *is* required. But 
when compiling kdebase, an installed and working kdelibs is required. So I'd 
say if there is no special use for zlib in the module, the check can be 
removed.

What about perl ?
It is required e.g. for dcopidl, which is a perl script. But do we need to 
check for it, since the installed kdelibs should ensure that it's available ?

What about carbon (on OS X) ?
It is used in kdelibs/, but also somewhere else ?

If something is absolutely required for building KDE software (also non-svn 
software), then the check should go into FindKDE4Internal.cmake.
Otherwise it should be removed.

So what do you think ?

Bye
Alex
