# ITKConfig.cmake - ITK CMake configuration file used
# internally for remote modules calling 'find_package()'
# CMake function.
#
# This file is a minimal implementation of ITKConfig.cmake
# that should only be used internally when configuring ITK.
# Some remote modules contain an 'example' folder. The
# example folder is designed to compile both from
# within the source tree of the module and as an independent
# project. This requires to be able to use the CMake function
# 'find_package(ITK)'. When compiled as part of ITK, this
# function needs to be able to find the file ITKConfig.cmake
# which can only be defined at the end of configuring ITK
# as it needs all the ITK CMake variables to be defined.
#
# This file provides a work around and is defined early in
# the ITK configuration process. Since it is run from within
# the ITK source tree, it does not need to define most ITK
# variables as those are already defined. It only ensures
# that the requested components are available.
# Compute set of requested modules.
if(ITK_FIND_COMPONENTS)
# Specific modules required by find_package(ITK) or optional and available.
set(ITK_MODULES_REQUESTED "")
foreach(M ${ITK_FIND_COMPONENTS})
if(ITK_FIND_REQUIRED_${M} OR M IN_LIST ITK_MODULES_ENABLED)
list(APPEND ITK_MODULES_REQUESTED "${M}")
endif()
endforeach()
else()
# No specific modules requested. Use all of them.
set(ITK_MODULES_REQUESTED "")
foreach(itk-module ${ITK_MODULES_ENABLED})
if(NOT ${itk-module}_IS_TEST)
list(APPEND ITK_MODULES_REQUESTED ${itk-module})
endif()

# Load requested modules and their dependencies into variables:
# ITK_LIBRARIES = Libraries to link
# ITK_INCLUDE_DIRS = Header file search path
# ITK_LIBRARY_DIRS = Library search path (for outside dependencies)
# ITK_RUNTIME_LIBRARY_DIRS = Runtime linker search path
# ITK_FACTORY_NAMES = List of <module>::<factory>::<format> to register
# ITK_FACTORY_LIST = List of factories
# ITK_<factory_name> = List of formats for each factory
