CMP0103 — CMake 4.0.1 Documentation (original) (raw)

Added in version 3.18.

Multiple calls to export() command with same FILE withoutAPPEND 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 toexport() 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.
