[cmake-developers] Changing FOLDER property of ALL_BUILD and RUN_TESTS targets in VS

[Robert Dailey]

I have the following CMake code:

get_property( predefined_folder GLOBAL PROPERTY PREDEFINED_TARGETS_FOLDER )

set_target_properties( ALL_BUILD PROPERTIES FOLDER ${predefined_folder} )

if( BUILD_TESTING )
    set_target_properties( RUN_TESTS PROPERTIES FOLDER "Testing" )
endif()

However this fails stating those targets do not exist. Is there a way
I can make this work? I'd like to organize these CMake targets in my
own way in the Visual Studio solution. There have been topics
regarding this on the mailing list in the past, but they have gone
unanswered.

Specifically, why are these targets treated as if they do not exist?
Does CMake only allow you to set properties on targets created
directly by the scripts themselves (i.e. no built-in targets can be
affected)?

I'm happy to contribute a patch to this if needed.

Thanks in advance.
