# - Find Corrade
#
# Basic usage:
#  find_package(Corrade [REQUIRED])
# This module tries to find Corrade library and then defines:
#  CORRADE_FOUND                    - True if Corrade library is found
#  CORRADE_INCLUDE_DIR              - Include dir for Corrade
#  CORRADE_INTERCONNECT_LIBRARIES   - Corrade Interconnect library and
#   dependent libraries
#  CORRADE_UTILITY_LIBRARIES        - Corrade Utility library and
#   dependent libraries
#  CORRADE_PLUGINMANAGER_LIBRARIES  - Corrade PluginManager library and
#   dependent libraries
#  CORRADE_TESTSUITE_LIBRARIES      - Corrade TestSuite library and
#   dependent libraries
#  CORRADE_RC_EXECUTABLE            - Corrade resource compiler executable
# Additionally these variables are defined for internal usage:
#  CORRADE_INTERCONNECT_LIBRARY     - Corrade Interconnect library (w/o
#   dependencies)
#  CORRADE_UTILITY_LIBRARY          - Corrade Utility library (w/o
#   dependencies)
#  CORRADE_PLUGINMANAGER_LIBRARY    - Corrade Plugin manager library (w/o
#   dependencies)
#  CORRADE_TESTSUITE_LIBRARY        - Corrade TestSuite library (w/o
#   dependencies)
# Corrade configures the compiler to use C++11 standard. Additionally you can
# use CORRADE_CXX_FLAGS to enable additional pedantic set of warnings and enable
# hidden visibility by default.
#
# If Corrade library is found, these macros and functions are defined:
#
#
# Add unit test using Corrade's TestSuite.
#  corrade_add_test(test_name
#                   sources...
#                   [LIBRARIES libraries...])
# Test name is also executable name. You can also specify libraries to link
# with instead of using target_link_libraries(). CORRADE_TESTSUITE_LIBRARIES
# are linked atuomatically to each test. Note that the enable_testing()
# function must be called explicitly.
#
#
# Compile data resources into application binary.
#  corrade_add_resource(name group_name
#                       file [ALIAS alias]
#                       [file1 [ALIAS alias1]...])
# Depends on corrade-rc, which is part of Corrade utilities. This command
# generates resource file with group group_name from given files 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. Example usage:
#  corrade_add_resource(name group_name file1 ALIAS alias1 file2 file3)
#  add_executable(app source1 source2 ... ${name})
#
# Add dynamic plugin.
#  corrade_add_plugin(plugin_name install_dir metadata_file
#                     sources...)
# The macro adds preprocessor directive CORRADE_DYNAMIC_PLUGIN. Additional
# libraries can be linked in via target_link_libraries(plugin_name ...). If
# install_dir is set to CMAKE_CURRENT_BINARY_DIR (e.g. for testing purposes),
# the files are copied directly, without need to run 'make install'.
#
#
# Add static plugin.
#  corrade_add_static_plugin(static_plugins_variable
#                            plugin_name metadata_file
#                            sources...)
# The macro adds preprocessor directive CORRADE_STATIC_PLUGIN. Additional
# libraries can be linked in via target_link_libraries(plugin_name ...). Plugin
# library name will be appended to static_plugins_variable and the variable is
# meant to be used for linking plugins to main executable/library, e.g:
#  target_link_libraries(app lib1 lib2 ... ${static_plugins_variable})
# This variable is set with parent scope to be available in parent directory.
# If there are more intermediate directories between plugin directory and main
# executable directory, the variable can be propagated to parent scope like
# this:
#  set(static_plugins_variable ${static_plugins_variable} PARENT_SCOPE)
#
# Find and install DLLs for bundling with Windows build.
#  corrade_bundle_dlls(library_install_dir
#                      dlls...
#                      [PATHS paths...])
# It is possible to specify also additional paths for searching. DLL names can
# also contain paths, they will be installed into exact specified path. If an
# DLL is not found, fatal error message is printed.
