|
:command:`add_test` honors :variable:`CMAKE_CROSSCOMPILING_EMULATOR` only
|
|
when :variable:`cross-compiling <CMAKE_CROSSCOMPILING>`.
|
|
|
|
In CMake 3.28 and below, :command:`add_test` unconditionally used the
|
|
:prop_tgt:`CROSSCOMPILING_EMULATOR` target property (initialized by the
|
|
:variable:`CMAKE_CROSSCOMPILING_EMULATOR` variable) to run test commands
|
|
naming executable targets. CMake 3.29 and above prefer to use the emulator
|
|
only when the :variable:`CMAKE_CROSSCOMPILING` variable is enabled. The
|
|
:variable:`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 :command:`add_test` to use
|
|
the :prop_tgt:`CROSSCOMPILING_EMULATOR` target property unconditionally.
|
|
The ``NEW`` behavior for this policy is for :command:`add_test` to use
|
|
the :prop_tgt:`CROSSCOMPILING_EMULATOR` target property only when
|
|
:variable:`cross-compiling <CMAKE_CROSSCOMPILING>`.
|
|
|
|
This policy was introduced in CMake version 3.29. Use the
|
|
:command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.
|
|
Unlike many policies, CMake version |release| does *not* warn
|
|
when this policy is not set and simply uses ``OLD`` behavior.
