New in version 3.18.
Multiple calls to export()
command with same FILE
without
APPEND
is no longer allowed.
In CMake 3.17 and below, multiple calls to export()
command with the
same FILE
without APPEND
are accepted silently but only the last
occurrence is taken into account during the generation.
- The
OLD
behavior for this policy is to ignore the multiple occurrences of export()
command except the last one.
The NEW
behavior of this policy is to raise an error on second call to
export()
command with same FILE
without APPEND
.
This policy was introduced in CMake version 3.18. CMake version
3.20.6 warns when the policy is not set and uses OLD
behavior.
Use the cmake_policy()
command to set it to OLD
or NEW
explicitly.
Note
The OLD
behavior of a policy is
deprecated by definition
and may be removed in a future version of CMake.
