Summary0013080: CTEST_CMAKE_COMMAND ignored by "ctest_*" command.
Description
If CTEST_CMAKE_COMMAND is set within a ctest script, its value isn't used.


If not explicitly set, should CTEST_CMAKE_COMMAND default to the value of cmake corresponding to the ctest program used to run the script ?
Steps To ReproduceThe attached archive bundle a very simple example illustrating the issue. I reproduced the problem using the following version of CMake/CTest:




Test case1:

~/Dashboards/Support/cmake-2.8.7-Linux-i386/bin/ctest -S drive_build.ctest -VV

Within drive_build.ctest:
   CTEST_CMAKE_COMMAND: /home/jchris/Dashboards/Support/cmake-2.8.8-rc1-Linux-i386/bin/cmake

Within CMakeLists.txt:
   cmake_minimum_required(VERSION 2.8.8)




Test case2

~/Dashboards/Support/cmake-2.8.6-Linux-i386/bin/ctest -S drive_build.ctest -VV

Within drive_build.ctest:
   CTEST_CMAKE_COMMAND: /home/jchris/Dashboards/Support/cmake-2.8.7-Linux-i386/bin/cmake

Within CMakeLists.txt:
    cmake_minimum_required(VERSION 2.8.7)

CTEST_CMAKE_COMMAND is intended to be a read-only variable. You should not set it within a ctest script.

By default, the ctest_configure command will use the cmake corresponding to the ctest being used to drive the script.

If you want to override it to use a different cmake explicitly for the configure step, you should set CTEST_CONFIGURE_COMMAND to customize the full command line of the configure step. See the code in Source/CTest/cmCTestConfigureCommand.cxx for details.

Thanks for clarification.

It's just that I initially based my understanding of this variable looking at existing scripts ...

It probably mean that the example reported here [1] should be updated.

Additionally, all our script within the "DashboardScripts" CVS repo all set this variable without using it directly in the script. Probably the evil "copy/paste" effect ...

Ah.... those things you point to are "old style" (pre-ctest_configure(), pre-ctest_build()) ctest scripts.

So we probably do support setting that var for old-style scripts.

But if you are using ctest_configure and ctest_build commands, you are by definition using a new-style script (2.4+) and should avoid setting CTEST_CMAKE_COMMAND. It's not used in new-style scripts.

(I forgot about those old style scripts already...)

Very true .. also forgot about that.

Before closing that issue, one last question:

Would it make sens to have CTEST_CMAKE_COMMAND available within a ctest script if it's invoked using "ctest -S </path/to/script>" ?

Or say differently is that variable expected to be valid when invoking a script that way ?

Try CMAKE_COMMAND : that should give you the full path to the corresponding CMake.

Even better, run this code in any CMake script/CMakeLists context to see what variables are defined and what their values are:

  get_cmake_property(vs VARIABLES)
  foreach(v ${vs})
    message("${v}='${${v}}'")
  endforeach()

Extra - thanks for the hint :) I believe the issue can now be closed.


FYI - Assuming -VV is used, within a ctest script message(STATUS "Hello") won't output anything whereas message("Hello") will output text.
