#.rst:
# ECMQtDeclareLoggingCategory
# ---------------------------
#
# Generate declarations for logging categories in Qt5.
#
# ::
#
# ecm_qt_declare_logging_category(<sources_var>
# HEADER <filename>
# IDENTIFIER <identifier>
# CATEGORY_NAME <category_name>
# [DEFAULT_SEVERITY
# <Debug|Info|Warning|
# Critical|Fatal>])
#
# A header file, ``<filename>``, will be generated along with a corresponding
# source file, which will be added to ``<sources_var>``. These will provide a
# QLoggingCategory category that can be referred to from C++ code using
# ``<identifier>``, and from the logging configuration using
# ``<category_name>``.
#
# If ``<filename>`` is not absolute, it will be taken relative to the current
# binary directory.
#
# If the code is compiled against Qt 5.4 or later, by default it will only log
# output that is at least the severity specified by ``DEFAULT_SEVERITY``, or
# "Warning" level if ``DEFAULT_SEVERITY`` is not given. Note that, due to a
# bug in Qt 5.5, "Info" may be treated as more severe than "Fatal".
#
# ``<identifier>`` may include namespaces (eg: ``foo::bar::IDENT``).
#
# Since 5.14.0.
