Every policy's documentation has a paragraph on what version of CMake introduced it, how to set the policy, and whether CMake warns if the policy is not set. The wording of this paragraph has diverged across policies over time. Factor the paragraph out into a standard advice document included by every policy.

Duplicate binary directories are not allowed.
|
|
|
|
CMake 2.6.3 and below silently permitted add_subdirectory() calls to
|
|
create the same binary directory multiple times. During build system
|
|
generation files would be written and then overwritten in the build
|
|
tree and could lead to strange behavior. CMake 2.6.4 and above
|
|
explicitly detect duplicate binary directories. CMake 2.6.4 always
|
|
considers this case an error. In CMake 2.8.0 and above this policy
|
|
determines whether or not the case is an error. The ``OLD`` behavior for
|
|
this policy is to allow duplicate binary directories. The NEW
|
|
behavior for this policy is to disallow duplicate binary directories
|
|
with an error.
