[CMake] Undocumented change of behavior when using EXCLUDE_FROM_ALL

[Jakub Imriska]

Hi CMake community,

the option EXCLUDE_FROM_ALL
<https://cmake.org/cmake/help/v3.14/prop_dir/EXCLUDE_FROM_ALL.html?highlight=exclude_from_all>
of *add_subdirectory* command affects in CMake 3.14.3 the content of the
Visual Studio solution file in the added subdirectory.
The difference is subtle: if the subdirectory A added with EXCLUDE_FROM_ALL
from source root contains another subdirectory B, a solution file in A
does *not
contain* project from B.
The behavior changed between versions 3.13.5 and 3.14.3. Tested also on
3.15.0, which produces same output as 3.14.3.Observed on Win 10 using *Visual
Studio 16 2019* and *Visual Studio 12 2013 Win64 *generators.
Test with *CodeBlocks - Unix Makefiles *generator does not show this issue.

Is there a way to retain the old behavior?
Thanks for an advice.

-------------------------------------------------------------------
Minimal example (attached):

$ cat CMakeLists.txt
cmake_minimum_required(VERSION 2.8)
project(main)
add_subdirectory(subdir EXCLUDE_FROM_ALL)

$ cat subdir/CMakeLists.txt
project(utilities)
add_subdirectory(subsubdir)

$ cat subdir/subsubdir/CMakeLists.txt
project(util)
add_executable(util util.cpp)

With CMake 3.13.5 the utilities solution file contains project util,
whereas with CMake 3.14.3 or 3.15.0 it does not.
