cmake and linking issues

[Giorgos Tsiapaliokas]

Hello,

I have came across to some buildsystem issues.

if I don't have the KDE4Support and KDELibs4 with this *exact*
order, cmake will fail. Without this order cmake fails in plasma-framework
and in plasmate. I have attached the output from cmake.

find_package(KDE4Support REQUIRED NO_MODULE)
find_package(KDELibs4 REQUIRED NO_MODULE)

So should the find_package be written like this?
Is it normal to fail otherwise?


The second issue is in plasmate[frameworks-scratch] we have a KDateTime
linking error,
I have attached the error.


thanks
