# Find Corrade
# ------------
#
# Finds the Corrade library. Basic usage::
#
#  find_package(Corrade REQUIRED)
#
# This module tries to find the base Corrade library and then defines the
# following:
#
#  Corrade_FOUND                  - Whether the base library was found
#  CORRADE_LIB_SUFFIX_MODULE      - Path to CorradeLibSuffix.cmake module
#  CORRADE_INCLUDE_INSTALL_PREFIX - Prefix where to put platform-independent
#   include and other files, defaults to ``.``. If a relative path is used,
#   it's relative to :variable:`CMAKE_INSTALL_PREFIX`.
#
# This command will try to find only the base library, not the optional
# components, which are:
#
#  Containers                   - Containers library
#  PluginManager                - PluginManager library
#  TestSuite                    - TestSuite library
#  Utility                      - Utility library
#  rc                           - corrade-rc executable
#
# Example usage with specifying additional components is::
#
#  find_package(Corrade REQUIRED Utility TestSuite)
#
# For each component is then defined:
#
#  Corrade_*_FOUND              - Whether the component was found
#  Corrade::*                   - Component imported target
#
# The package is found if either debug or release version of each library is
# found. If both debug and release libraries are found, proper version is
# chosen based on actual build configuration of the project (i.e. Debug build
# is linked to debug libraries, Release build to release libraries).
#
# Corrade conditionally defines ``CORRADE_IS_DEBUG_BUILD`` preprocessor
# variable in case build configuration is ``Debug`` (not Corrade itself, but
# build configuration of the project using it). Useful e.g. for selecting
# proper plugin directory.
#
# Corrade defines the following custom target properties:
#
#  CORRADE_CXX_STANDARD         - C++ standard to require when compiling given
#   target. Does nothing if :variable:`CMAKE_CXX_FLAGS` already contains
#   particular standard setting flag or if given target contains
#   :prop_tgt:`CMAKE_CXX_STANDARD` property. Allowed value is 11, 14 or 17.
#  INTERFACE_CORRADE_CXX_STANDARD - C++ standard to require when using given
#   target. Does nothing if :variable:`CMAKE_CXX_FLAGS` already contains
#   particular standard setting flag or if given target contains
#   :prop_tgt:`CMAKE_CXX_STANDARD` property. Allowed value is 11, 14 or 17.
#  CORRADE_USE_PEDANTIC_FLAGS   - Enable additional compiler/linker flags.
#   Boolean.
#
# These properties are inherited from directory properties, meaning that if you
# set them on directories, they get implicitly set on all targets in given
# directory (with a possibility to do target-specific overrides). All Corrade
# libraries have the :prop_tgt:`INTERFACE_CORRADE_CXX_STANDARD` property set to
# 11, meaning that you will always have at least C++11 enabled once you link to
# any Corrade library.
#
# Features of found Corrade library are exposed in these variables:
#
#  CORRADE_MSVC2019_COMPATIBILITY - Defined if compiled with compatibility

# Additionally these variables are defined for internal usage:
#

#   enabled
#
# Workflows without :prop_tgt:`IMPORTED` targets are deprecated and the
# following variables are included just for backwards compatibility and only if
# :variable:`CORRADE_BUILD_DEPRECATED` is enabled:
#
#  CORRADE_CXX_FLAGS            - Pedantic compile flags. Use
#   :prop_tgt:`CORRADE_USE_PEDANTIC_FLAGS` property or
#   :variable:`CORRADE_PEDANTIC_COMPILER_DEFINITIONS` /
#   :variable:`CORRADE_PEDANTIC_COMPILER_OPTIONS` list variables instead.
#
# Corrade provides these macros and functions:
#
# .. command:: corrade_add_test
#
# Add unit test using Corrade's TestSuite::
#
#  corrade_add_test(<test name>
#                   <sources>...
#                   [LIBRARIES <libraries>...]
#                   [FILES <files>...]
#                   [ARGUMENTS <arguments>...])
#
# Test name is also executable name. You can use ``LIBRARIES`` to specify
# libraries to link with instead of using :command:`target_link_libraries()`.
# The ``Corrade::TestSuite`` target is linked automatically to each test. Note
# that the :command:`enable_testing()` function must be called explicitly.
# Arguments passed after ``ARGUMENTS`` will be appended to the test
# command line. ``ARGUMENTS`` are supported everywhere except when
# ``CORRADE_TESTSUITE_TARGET_XCTEST`` is enabled.
#
# You can list files needed by the test in the ``FILES`` section. If given
# filename is relative, it is treated relatively to `CMAKE_CURRENT_SOURCE_DIR`.
# The files are added to the :prop_test:`REQUIRED_FILES` target property. On
# Emscripten they are bundled to the executable and available in the virtual
# filesystem root. On Android they are copied along the executable to the
# target. In case of Emscripten and Android, if the file is absolute or
# contains ``..``, only the leaf name is used. Alternatively you can have a
# filename formatted as ``<input>@<output>``, in which case the ``<input>`` is
# treated as local filesystem location and ``<output>`` as remote/virtual
# filesystem location. The remote location can't be absolute or contain ``..``
# / ``@`` characters.
#
# Unless :variable:`CORRADE_TESTSUITE_TARGET_XCTEST` is set, test cases on iOS
# targets are created as bundles with bundle identifier set to CMake project
# name by default. Use the cache variable :variable:`CORRADE_TESTSUITE_BUNDLE_IDENTIFIER_PREFIX`
# to change it to something else.
#
# .. command:: corrade_add_resource
#
# Compile data resources into application binary::
#
#  corrade_add_resource(<name> <resources.conf>)
#
# Depends on ``Corrade::rc``, which is part of Corrade utilities. This command
# generates resource data using given configuration file in current build
# directory. Argument name is name under which the resources can be explicitly
# loaded. Variable ``<name>`` contains compiled resource filename, which is
# then used for compiling library / executable. On CMake >= 3.1 the
# `resources.conf` file can contain UTF-8-encoded filenames. Example usage::
#
#  corrade_add_resource(app_resources resources.conf)
#  add_executable(app source1 source2 ... ${app_resources})
#
# .. command:: corrade_add_plugin
#
# Add dynamic plugin::
#
#  corrade_add_plugin(<plugin name>
#                     "<debug binary install dir>;<debug library install dir>"
#                     "<release binary install dir>;<release library install dir>"
#                     <metadata file>
#                     <sources>...)
#
# The macro adds a preprocessor directive ``CORRADE_DYNAMIC_PLUGIN`` when
# compiling ``<sources>``. Additional libraries can be linked in via
# :command:`target_link_libraries(plugin_name ...) <target_link_libraries>`.
# On DLL platforms, the plugin DLLs and metadata files are put into
# ``<debug binary install dir>`` / ``<release binary install dir>`` and the
# ``*.lib`` files into ``<debug library install dir>`` /
# ``<release library install dir>``. On non-DLL platforms everything is put
# into ``<debug library install dir>`` / ``<release library install dir>``.
#
# If the plugin interface disables plugin metadata files, the
# ``<metadata file>`` can be set to ``""``, in which case no metadata file is
# copied anywhere. Otherwise the metadata file is copied and renamed to
# ``<plugin name>``, retaining its original extension.
#
#  corrade_add_plugin(<plugin name>
#                     <debug install dir>
#                     <release install dir>
#                     <metadata file>
#                     <sources>...)
#
# Unline the above version this puts everything into ``<debug install dir>`` on
# both DLL and non-DLL platforms. If ``<debug install dir>`` is set to
# :variable:`CMAKE_CURRENT_BINARY_DIR` (e.g. for testing purposes), the files
# are copied directly, without the need to perform install step. Note that the
# files are actually put into configuration-based subdirectory, i.e.
# ``${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}``. See documentation of
# :variable:`CMAKE_CFG_INTDIR` variable for more information.
#
# .. command:: corrade_add_static_plugin
#
# Add static plugin::
#
#  corrade_add_static_plugin(<plugin name>
#                            "<binary install dir>;<library install dir>"
#                            <metadata file>
#                            <sources>...)
#
# The macro adds a preprocessor directive ``CORRADE_STATIC_PLUGIN`` when
# compiling ``<sources>``. Additional libraries can be linked in via
# :command:`target_link_libraries(plugin_name ...) <target_link_libraries>`.
# The ``<binary install dir>`` is ignored and included just for compatibility
# with the :command:`corrade_add_plugin` command, everything is installed into
# ``<library install dir>``. Note that plugins built in debug configuration
# (e.g. with :variable:`CMAKE_BUILD_TYPE` set to ``Debug``) have ``"-d"``
# suffix to make it possible to have both debug and release plugins installed
# alongside each other.
#
# If the plugin interface disables plugin metadata files, the
# ``<metadata file>`` can be set to ``""``, in which case no metadata file is
# used. Otherwise the metadata file is bundled and renamed to
# ``<plugin name>``, retaining its original extension.
#
#  corrade_add_static_plugin(<plugin name>
#                            <install dir>
#                            <metadata file>
#                            <sources>...)
#
# Equivalent to the above with ``<library install dir>`` set to ``<install dir>``.
# If ``<install dir>`` is set to :variable:`CMAKE_CURRENT_BINARY_DIR` (e.g. for
# testing purposes), no installation rules are added.
#
# .. command:: corrade_find_dlls_for_libs
#
# Find corresponding DLLs for library files::
#
#  corrade_find_dlls_for_libs(<output variable> <libs>...)
#
# Available only on Windows, for all ``*.lib`` files tries to find
# corresponding DLL file. Useful for bundling dependencies for e.g. WinRT
# packages.
