# 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
#
# This command will try to find only the base library, not the optional
# components, which are:
#
# Containers - Containers library
# Interconnect - Interconnect library
# Main - Main 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_MSVC_COMPATIBILITY - Defined if compiled with compatibility
# mode for MSVC 2019+ without the /permissive- flag set
# CORRADE_MSVC2017_COMPATIBILITY - Defined if compiled with compatibility

# Default are shared libraries.
# CORRADE_BUILD_STATIC_UNIQUE_GLOBALS - Defined if static libraries keep their
# globals unique even across different shared libraries. Enabled by default
# for static builds.
# CORRADE_BUILD_MULTITHREADED - Defined if compiled in a way that makes it
# possible to safely use certain Corrade features simultaneously in multiple
# threads

# optimized for multiple architectres with the best matching variant selected
# at runtime based on detected CPU features
# CORRADE_TARGET_UNIX - Defined if compiled for some Unix flavor
# (Linux, BSD, macOS)

# compatible Clang
# CORRADE_TARGET_CLANG - Defined if compiling with Clang or any of its
# variants
# CORRADE_TARGET_APPLE_CLANG - Defined if compiling with Apple's Clang
# CORRADE_TARGET_CLANG_CL - Defined if compiling with Clang-CL (Clang

# XCTest
# CORRADE_UTILITY_USE_ANSI_COLORS - Defined if ANSI escape sequences are used
# for colored output with Utility::Debug on Windows
#
# Additionally these variables are defined for internal usage:
#
# CORRADE_INCLUDE_DIR - Root include dir
# CORRADE_*_LIBRARY_DEBUG - Debug version of given library, if found
# CORRADE_*_LIBRARY_RELEASE - Release version of given library, if found
# CORRADE_*_EXECUTABLE - Location of given executable, if found
# CORRADE_*_EXECUTABLE_EMULATOR - Emulator to run CORRADE_*_EXECUTABLE, if a
# non-native version was found when cross-compiling
# CORRADE_USE_MODULE - Path to UseCorrade.cmake module (included
# automatically)

# CORRADE_CXX{11,14,17,20}_STANDARD_FLAG - Compiler flag to use for targeting
# C++11, 14, 17 or 20 in cases where it's not possible to use
# :prop_tgt:`CORRADE_CXX_STANDARD`. Not defined if a standard switch is
# already present in :variable:`CMAKE_CXX_FLAGS`.
#
# 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 ... ${app_resources})
#
# .. command:: corrade_add_plugin
#
# Add dynamic plugin::
#
# corrade_add_plugin(<plugin name>
# "<debug binary install dir>;<debug library install dir>"
# "<release binary install dir>;<release library install dir>"
# <metadata file>
# <sources>...)
#
# The macro adds a preprocessor directive ``CORRADE_DYNAMIC_PLUGIN`` when
# compiling ``<sources>``. Additional libraries can be linked in via
# :command:`target_link_libraries(plugin_name ...) <target_link_libraries>`.
# On DLL platforms, the plugin DLLs and metadata files are put into
# ``<debug binary install dir>`` / ``<release binary install dir>`` and the
# ``*.lib`` files into ``<debug library install dir>`` /
# ``<release library install dir>``. On non-DLL platforms everything is put
# into ``<debug library install dir>`` / ``<release library install dir>``.
#
# If the plugin interface disables plugin metadata files, the
# ``<metadata file>`` can be set to ``""``, in which case no metadata file is
# copied anywhere. Otherwise the metadata file is copied and renamed to
# ``<plugin name>``, retaining its original extension.
#
# corrade_add_plugin(<plugin name>
# <debug install dir>
# <release install dir>
# <metadata file>
# <sources>...)
#
# Unlike the above version this puts everything into ``<debug install dir>`` on
# both DLL and non-DLL platforms. If ``<debug install dir>`` is set to
# :variable:`CMAKE_CURRENT_BINARY_DIR` (e.g. for testing purposes), the files
# are copied directly, without the need to perform install step. Note that the
# files are actually put into configuration-based subdirectory, i.e.
# ``${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.

# libvulkan.so *should* link against pthread on its own, but in some rare
# corner cases (like the 1.2.203 ArchLinux package) it doesn't -- most probably
# due to the vulkan loader wrongly using `-lpthread` instead of `-pthread` and
# then the linker DCEing out the reference to it based on some unfortunate
# combination of compiler/linker flags?
#
# In that case using drivers that rely on pthread (such as SwiftShader) would
# lead to a nasty std::system_error telling me to link to pthreads. As I can't
# have control over how the loader links to pthread or whether at all, and what
# random packaging issues happened in various distributions, I have to link to
# it explicitly to be immune against such issues.
