When building and testing CMake in a container with qemu user mode emulation, the expected termination with std::abort() in testUVProcessChainHelper leads qemu to emit an additional message about an uncaught signal. There appears to be no way to make qemu shut up, so any qemu message will be removed from the output during validation.

FindBISON
---------
Find ``bison`` executable and provide a macro to generate custom build rules.
The module defines the following variables:
``BISON_EXECUTABLE``
path to the ``bison`` program
``BISON_VERSION``
version of ``bison``
``BISON_FOUND``
"True" if the program was found
The minimum required version of ``bison`` can be specified using the
standard CMake syntax, e.g. :command:`find_package(BISON 2.1.3)`.
If ``bison`` is found, the module defines the macro::
BISON_TARGET(<Name> <YaccInput> <CodeOutput>
[COMPILE_FLAGS <flags>]
[DEFINES_FILE <file>]
[VERBOSE [<file>]]
[REPORT_FILE <file>]
)
which will create a custom rule to generate a parser. ``<YaccInput>`` is
the path to a yacc file. ``<CodeOutput>`` is the name of the source file
generated by bison. A header file is also be generated, and contains
the token list.
The options are:
``COMPILE_FLAGS <flags>``
Specify flags to be added to the ``bison`` command line.
``DEFINES_FILE <file>``
Specify a non-default header ``<file>`` to be generated by ``bison``.
``VERBOSE [<file>]``
Tell ``bison`` to write a report file of the grammar and parser.
If ``<file>`` is given, it specifies path the report file is copied to.
``[<file>]`` is left for backward compatibility of this module.
Use ``VERBOSE REPORT_FILE <file>``.
``REPORT_FILE <file>``
Specify a non-default report ``<file>``, if generated.
The macro defines the following variables:
``BISON_<Name>_DEFINED``
``True`` is the macro ran successfully
``BISON_<Name>_INPUT``
The input source file, an alias for <YaccInput>
``BISON_<Name>_OUTPUT_SOURCE``
The source file generated by bison
``BISON_<Name>_OUTPUT_HEADER``
The header file generated by bison
``BISON_<Name>_OUTPUTS``
All files generated by bison including the source, the header and the report
``BISON_<Name>_COMPILE_FLAGS``
Options used in the ``bison`` command line
Example usage:
.. code-block:: cmake
find_package(BISON)
BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp
DEFINES_FILE ${CMAKE_CURRENT_BINARY_DIR}/parser.h)
