Hello, all:

Overnight, I upgraded from KDE 4.5.1 to 4.6.3 and had a rude awakening this morning when I found that KDE had managed to, once again, break the Task Manager "force rows" behavior which had been fixed a few major releases ago. I found this lovely patch that had been applied:

https://svn.reviewboard.kde.org/r/5776/

And thus broken the functionality, and I want to recompile that particular plasmoid with the patch removed. However, I am completely unfamiliar with CMake or building anything at all, for that matter. All my programming is done in PHP which means I'm pretty much completely lost.

I'm in the midst of pulling down the kde-workspace tree with git, and already downloaded and modified a separate copy of the file in question to look the way it is supposed to. My only question is, how do I build it? I don't want to rebuild all of KDE, just the one module.

Thanks in advance.

Okay, quick update. Someone was kindly able to send me a file to help with the CMake part of the equation. But now I've got errors in compiling, even though I've installed every KDE-related -dev package I could find. Here's the output of "make":

Any thoughts on what I could do to make it build successfully?

Thanks.

I figured it out. There was a mistake in the CMakeLists.txt file that I randomly guessed was wrong. As soon as I fixed that, it built without issue.
