|
:module:`FindBISON` runs bison in :variable:`CMAKE_CURRENT_BINARY_DIR`
|
|
when executing.
|
|
|
|
The module provides a ``bison_target()`` command which generates BISON output.
|
|
In CMake 3.13 and below the command would generate a custom build rule that runs
|
|
``bison`` in the source directory. CMake 3.14 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 to the build
|
|
tree rather than the source.
|
|
|
|
This policy provides compatibility for projects that have not been updated
|
|
to expect the new behavior.
|
|
|
|
The ``OLD`` behavior for this policy is for ``bison_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`` and where
|
|
to generate implicit files.
