KDEFrameworkCompilerSettings
----------------------------

Set stricter compile and link flags for KDE Frameworks modules.

.. warning::
   Do not use this module for software which is not part of KDE-Frameworks.
   There is no guarantee for backward-compatibility in newer versions.

The :kde-module:`KDECompilerSettings` module is included and, in addition, various
defines that affect the Qt libraries are set to enforce certain
conventions.

For example, constructions like ``QString("foo")`` are prohibited, instead
forcing the use of QLatin1String or QStringLiteral, and some
Qt-defined keywords like signals and slots will not be defined.

.. note::
  It is recommended to include this module with the NO_POLICY_SCOPE
  flag, otherwise you may get spurious warnings with some versions of CMake.

Since pre-1.0.0.
#]=======================================================================]

# No-one else should be using this module, at least by the time when requiring
# ECM 5.85 as minimum, where also settings levels had been introduced for
# KDECompilerSettings to satisfy the needs for stricter out-of-the-box
# settings.
# So making a clear cut here by that condition and providing backward-compat
# support from a separate file with the old code, avoiding the need for
# further if()-else() when changing the settings for current KDE Frameworks.
