# This module can find the International Components for Unicode (ICU) libraries
#
# Requirements:
# - CMake >= 2.8.3 (for new version of find_package_handle_standard_args)
#
# The following variables will be defined for your use:
# - ICU_FOUND : were all of your specified components found?
# - ICU_INCLUDE_DIRS : ICU include directory
# - ICU_LIBRARIES : ICU libraries
# - ICU_VERSION : complete version of ICU (x.y.z)
# - ICU_VERSION_MAJOR : major version of ICU
# - ICU_VERSION_MINOR : minor version of ICU
# - ICU_VERSION_PATCH : patch version of ICU
# - ICU_<COMPONENT>_FOUND : were <COMPONENT> found? (FALSE for non specified component if it is not a dependency)
#
# For windows or non standard installation, define ICU_ROOT_DIR variable to point to the root installation of ICU. Two ways:
# - run cmake with -DICU_ROOT_DIR=<PATH>
# - define an environment variable with the same name before running cmake
# With cmake-gui, before pressing "Configure":
# 1) Press "Add Entry" button
# 2) Add a new entry defined as:
# - Name: ICU_ROOT_DIR
# - Type: choose PATH in the selection list
# - Press "..." button and select the root installation of ICU
#
# Example Usage:
#
# 1. Copy this file in the root of your project source directory
# 2. Then, tell CMake to search this non-standard module in your project directory by adding to your CMakeLists.txt:
# set(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR})
# 3. Finally call find_package() once, here are some examples to pick from
#
# Require ICU 4.4 or later
# find_package(ICU 4.4 REQUIRED)
#
# if(ICU_FOUND)
# add_executable(myapp myapp.c)
# include_directories(${ICU_INCLUDE_DIRS})
# target_link_libraries(myapp ${ICU_LIBRARIES})
# # with CMake >= 3.0.0, the last two lines can be replaced by the following
# target_link_libraries(myapp ICU::ICU)

#
# Prototype:
# icu_generate_resource_bundle([NAME <name>] [PACKAGE] [DESTINATION <location>] [FILES <list of files>])
#
# Common arguments:
# - NAME <name> : name of output package and to create dummy targets
# - FILES <file 1> ... <file N> : list of resource bundles sources
# - DEPENDS <target1> ... <target N> : required to package as library (shared or static), a list of cmake parent targets to link to
# Note: only (PREVIOUSLY DECLARED) add_executable and add_library as dependencies
# - DESTINATION <location> : optional, directory where to install final binary file(s)
# - FORMAT <name> : optional, one of none (ICU4C binary format, default), java (plain java) or xliff (XML), see below
#
# Arguments depending on FORMAT:
# - none (default):
# * PACKAGE : if present, package all resource bundles together. Default is to stop after building individual *.res files
# * TYPE <name> : one of :
# + common or archive (default) : archive all ressource bundles into a single .dat file
# + library or dll : assemble all ressource bundles into a separate and loadable library (.dll/.so)
# + static : integrate all ressource bundles to targets designed by DEPENDS parameter (as a static library)
# * NO_SHARED_FLAGS : only with TYPE in ['library', 'dll', 'static'], do not append ICU_C(XX)_SHARED_FLAGS to targets given as DEPENDS argument
# - JAVA:
# * BUNDLE <name> : required, prefix for generated classnames
# - XLIFF:
# (none)
#
#
# For an archive, the idea is to generate the following dependencies:
#
# root.txt => root.res \
# |
# en.txt => en.res |
# | => pkglist.txt => application.dat
# fr.txt => fr.res |
# |
# and so on /
#
# Lengend: 'A => B' means B depends on A
#
# Steps (correspond to arrows):
# 1) genrb (from .txt to .res)
# 2) generate a file text (pkglist.txt) with all .res files to put together
# 3) build final archive (from *.res/pkglist.txt to .dat)
