Summary

0009173: create policy for change to add_subdirectory() behavior

Description

CMake 2.6.4 introduced a "bug fix" that prevents add_subdirectory() from being called on the same source directory multiple times.

For at least two of us (Floca Ralf Omar and I), this bug fix breaks our existing CMake scripts.

I propose that a policy be created so that users like Ralf and I can disable the new add_subdirectory() behavior until we have time to update our scripts to use a different strategy that does not rely on adding subdirectories multiple times.

Brad King agreed that this behavior could be controlled with a policy:

http://www.cmake.org/pipermail/cmake/2009-June/030193.html [^]

The rest of that thread has good discussion about the nature of the problem and why we want this policy.

Thanks,
tyler
