CMP0103ΒΆ
Added 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
OLDbehavior 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.
It may be set by cmake_policy() or cmake_minimum_required().
If it is not set, CMake warns, and uses OLD behavior.
Note
The OLD behavior of a policy is
deprecated by definition
and may be removed in a future version of CMake.
