Set CMAKE_*_OUTPUT_DIRECTORY to run tests without installing.

Authored by dfaure on Aug 8 2017, 8:46 AM.



For compatibility reasons, this is only enabled when projects
upgrade their find_package(ECM) line to request a version >= 5.38.
A little bit like cmake policies: just upgrading ECM is compatible,
while increasing the required version can change behaviour.

Test Plan

Tested make test in all KF5 frameworks; I have patches
for some of them which I can't commit until this is in.

Fixed with 7e7b6da

Ooops, sorry. I had heavily tested ... a somewhat different version of the patch :(

Thanks for the fixes.

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 D7347 which make use of the here undocumented ${CMAKE_LIBRARY_OUTPUT_DIRECTORY} and then also point to yet another documentation source, on, instead of these docs, indicate things need some work here.

Patch for more docu:

BTW CMAKE_LIBRARY_OUTPUT_DIRECTORY is not undocumented, it's part of the cmake documentation:

Where to put all the :ref:`LIBRARY <Library Output Artifacts>`
target files when built.

This variable is used to initialize the ``LIBRARY_OUTPUT_DIRECTORY``
property on all the targets.  See that target property for additional
