:module:`FindFLEX` runs ``flex`` in directory
|
|
:variable:`CMAKE_CURRENT_BINARY_DIR` when executing.
|
|
|
|
The module provides a ``FLEX_TARGET`` macro which generates FLEX output.
|
|
In CMake 3.16 and below the macro would generate a custom command that runs
|
|
``flex`` in the current source directory. CMake 3.17 and later prefer to
|
|
run it in the build directory and use :variable:`CMAKE_CURRENT_BINARY_DIR`
|
|
as the ``WORKING_DIRECTORY`` of its :command:`add_custom_command` invocation.
|
|
This ensures that any implicitly generated file is written relative to the
|
|
build tree rather than the source tree, unless the generated file is
|
|
provided as absolute path.
|
|
|
|
This policy provides compatibility for projects that have not been updated
|
|
to expect the new behavior.
|
|
|
|
The ``OLD`` behavior for this policy is for ``FLEX_TARGET`` to use
|
|
the current source directory for the ``WORKING_DIRECTORY`` and where
|
|
to generate implicit files. The ``NEW`` behavior of this policy is to
|
|
use the current binary directory for the ``WORKING_DIRECTORY`` relative to
|
|
which implicit files are generated unless provided as absolute path.
|
|
|
|
This policy was introduced in CMake version 3.17. 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.
