#.rst:
# ECMGeneratePkgConfigFile
# ------------------------
#
# Generate a `pkg-config <http://www.freedesktop.org/wiki/Software/pkg-config/>`_
# file for the benefit of
# `autotools <http://www.gnu.org/software/automake/manual/html_node/Autotools-Introduction.html>`_-based
# projects.
#
# ::
#
# ecm_generate_pkgconfig_file(BASE_NAME <baseName>
# [LIB_NAME <libName>]
# [DEPS "<dep> [<dep> [...]]"]
# [FILENAME_VAR <filename_variable>]
# [INCLUDE_INSTALL_DIR <dir>]
# [LIB_INSTALL_DIR <dir>]
# [DEFINES -D<variable=value>...]
# [INSTALL])
#
# ``BASE_NAME`` is the name of the module. It's the name projects will use to
# find the module.
#
# ``LIB_NAME`` is the name of the library that is being exported. If undefined,
# it will default to the ``BASE_NAME``. That means the ``LIB_NAME`` will be set
# as the name field as well as the library to link to.
#
# ``FILENAME_VAR`` is specified with a variable name. This variable will
# receive the location of the generated file will be set, within the build
# directory. This way it can be used in case some processing is required. See
# also ``INSTALL``.
#
# ``INCLUDE_INSTALL_DIR`` specifies where the includes will be installed. If
# it's not specified, it will default to ``INSTALL_INCLUDEDIR``,
# ``CMAKE_INSTALL_INCLUDEDIR`` or just "include/" in case they are specified,
# with the BASE_NAME postfixed.
#
# ``LIB_INSTALL_DIR`` specifies where the library is being installed. If it's
# not specified, it will default to ``LIB_INSTALL_DIR``,
# ``CMAKE_INSTALL_LIBDIR`` or just "lib/" in case they are specified.
#
# ``DEFINES`` is a list of preprocessor defines that it is recommended users of
# the library pass to the compiler when using it.
#
# ``INSTALL`` will cause the module to be installed to the ``pkgconfig``
# subdirectory of ``LIB_INSTALL_DIR``, unless the ``ECM_PKGCONFIG_INSTALL_DIR``
# cache variable is set to something different. Note that the first call to
# ecm_generate_pkgconfig_file with the ``INSTALL`` argument will cause
# ``ECM_PKGCONFIG_INSTALL_DIR`` to be set to the cache, and will be used in any
# subsequent calls.
#
# To properly use this macro a version needs to be set. To retrieve it,
# ``ECM_PKGCONFIG_INSTALL_DIR`` uses ``PROJECT_VERSION``. To set it, use the
# project() command (only available since CMake 3.0) or the ecm_setup_version()
# macro.
#
# Example usage:
#
# .. code-block:: cmake
#
# ecm_generate_pkgconfig_file(
# BASE_NAME KF5Archive
# DEPS Qt5Core
# FILENAME_VAR pkgconfig_filename
# INSTALL
# )
#
# Since 1.3.0.
