Read `CMAKE_CROSSCOMPILING_EMULATOR` from an environment variable of the same name if not specified with `-D` or an initial cache value. Along with existing environment variable settings such as `CMAKE_TOOLCHAIN_FILE`, cross compilation configuration can be more completely set via environment variables.

CMAKE_CROSSCOMPILING_EMULATOR
|
|
-----------------------------
|
|
|
|
.. versionadded:: 3.3
|
|
|
|
This variable is only used when :variable:`CMAKE_CROSSCOMPILING` is on. It
|
|
should point to a command on the host system that can run executable built
|
|
for the target system.
|
|
|
|
.. versionadded:: 3.15
|
|
If this variable contains a :ref:`semicolon-separated list <CMake Language
|
|
Lists>`, then the first value is the command and remaining values are its
|
|
arguments.
|
|
|
|
.. versionadded:: 3.28
|
|
This variable can be initialized via an
|
|
:envvar:`CMAKE_CROSSCOMPILING_EMULATOR` environment variable.
|
|
|
|
The command will be used to run :command:`try_run` generated executables,
|
|
which avoids manual population of the ``TryRunResults.cmake`` file.
|
|
|
|
It is also used as the default value for the
|
|
:prop_tgt:`CROSSCOMPILING_EMULATOR` target property of executables.
