| |
| :module:`FindBISON` runs bison in :variable:`CMAKE_CURRENT_BINARY_DIR` |
| when executing. |
| |
| The module provides a ``BISON_TARGET`` macro which generates BISON output. |
| In CMake 3.13 and below the macro would generate a custom command 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. |
