Added in version 4.1.

Modules FindPython3, FindPython2 and FindPython enforce consistency of artifacts in cross-compiling mode.

Starting with CMake 4.1, Modules FindPython3, FindPython2 and FindPython apply, in cross-compiling mode (i.e. the CMAKE_CROSSCOMPILING variable is set to true), the following constraints to the requested components:

  • Interpreter or Compiler alone: the host artifacts will be searched.

  • Interpreter or Compiler with Development or any sub-component: The target artifacts will be searched. In this case, the CMAKE_CROSSCOMPILING_EMULATOR variable must be defined and will be used to execute the interpreter or the compiler.

This policy provides compatibility with projects that expect the legacy behavior.

The OLD behavior for this policy does not enforce consistency in cross-compiling mode and will, potentially, returns a mix of artifacts (i.e. host and target artifacts).

This policy was introduced in CMake version 4.1. It may be set by cmake_policy() or cmake_minimum_required(). If it is not set, CMake does not warn, 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.
