New in version 3.14.
FindBISON
runs bison in 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 CMAKE_CURRENT_BINARY_DIR
as the
WORKING_DIRECTORY
of its 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.
This policy was introduced in CMake version 3.14.
It may be set by cmake_policy()
or cmake_minimum_required()
.
If it is not set, CMake does not warn, and uses OLD
behavior.
Note
The OLD
behavior of a policy is
deprecated by definition
and may be removed in a future version of CMake.
