Trying to fix things for kdevelop tests, I have to report that as user of ECM this note does not really assist me, besides hinting there is random magic happening :(

So could you please add a comment telling what is that "layout" like, how does it help exactly running executables without installing? What other pre-conditions are need to be met? How should one rely on that layout in own cmake code?

Commits like https://phabricator.kde.org/D7347 which make use of the here undocumented `${CMAKE_LIBRARY_OUTPUT_DIRECTORY}` and then also point to yet another documentation source, on community.kde.org, instead of these docs, indicate things need some work here.
