CMP0158

New in version 3.29.

add_test() honors CMAKE_CROSSCOMPILING_EMULATOR only when cross-compiling.

In CMake 3.28 and below, add_test() unconditionally used the CROSSCOMPILING_EMULATOR target property (initialized by the CMAKE_CROSSCOMPILING_EMULATOR variable) to run test commands naming executable targets. CMake 3.29 and above prefer to use the emulator only when the CMAKE_CROSSCOMPILING variable is enabled. The CMAKE_TEST_LAUNCHER variable may be used instead when not cross-compiling. This policy provides compatibility for projects that have not been updated.

The OLD behavior for this policy is for add_test() to use the CROSSCOMPILING_EMULATOR target property unconditionally. The NEW behavior for this policy is for add_test() to use the CROSSCOMPILING_EMULATOR target property only when cross-compiling.

This policy was introduced in CMake version 3.29. 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.
