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 expand variables in target source entries.
|
|
|
|
CMake 2.8.12 and lower performed an extra layer of variable expansion
|
|
when evaluating source file names::
|
|
|
|
set(a_source foo.c)
|
|
add_executable(foo \${a_source})
|
|
|
|
.. note: no cmake highlighting since this syntax is deprecated
|
|
|
|
This was undocumented behavior.
|
|
|
|
The ``OLD`` behavior for this policy is to expand such variables when processing
|
|
the target sources. The ``NEW`` behavior for this policy is to issue an error
|
|
if such variables need to be expanded.
