[cmake-developers] Fwd: Exiting CMake (should message(send_error ) show a call stack)

[William A. Hoffman]

Here is a message from one of the kde lists:


>Howdy CMake Gurus,

>Is there a little more graceful way of exiting other than message(FATAL_ERROR "message") ??

>For example, in the MACRO_DISPLAY_FEATURE_LOG() macro I want to exit if there

>are missing and then exit.

>But I don't want to panic the user with messages like:

>  CMake Error: Error in cmake code at
>  /data/kde/trunk/KDE/kdepimlibs/CMakeLists.txt:1:
>  MESSAGE some message
>  Current CMake stack: /data/kde/trunk/KDE/kdepimlibs/CMakeLists.txt

In the past MESSAGE(FATAL_ERROR "some message") only printed some message and
cmake stopped processing.   At some point the call stack was added.   Is this
really what should happen?  Maybe we need a MESSAGE(ABORT that shows the call
stack and the FATAL_ERROR goes back to the way it was.  This "feature" slipped
in between 2.4.2 and 2.4.3.
