CMP0158ΒΆ
Added 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.
