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.

-------
|
|
|
|
Do not re-expand variables in include and link information.
|
|
|
|
CMake 2.8.10 and lower re-evaluated values given to the
|
|
include_directories, link_directories, and link_libraries commands to
|
|
expand any leftover variable references at the end of the
|
|
configuration step. This was for strict compatibility with VERY early
|
|
CMake versions because all variable references are now normally
|
|
evaluated during CMake language processing. CMake 2.8.11 and higher
|
|
prefer to skip the extra evaluation.
|
|
|
|
The ``OLD`` behavior for this policy is to re-evaluate the values for
|
|
strict compatibility. The ``NEW`` behavior for this policy is to leave
|
|
the values untouched.
