Heya,

Please try this with KDevelop 5.0 branch (check out kdevplatform.git 5.0 
branch, kdevelop.git 5.0 branch).

We've spent tons of time streamlining KDevelop for Windows on 5.0 -- we didn't 
do this for 4.7. And we won't spend time on doing so for 4.7.

When compiling KDevelop 5, you'll have to compile all of KF5, too, thus I 
recommend to use Emerge, a package manager-like user tool for building from 
source:
  https://techbase.kde.org/Getting_Started/Build/Windows/emerge

Hope that helps,
Kevin
