# https://github.com/astahl/poco-cmake/blob/master/cmake/FindPoco.cmake
# - finds the Poco C++ libraries
# This module finds the Applied Informatics Poco libraries.
# It supports the following components:
#
# Util (loaded by default)
# Foundation (loaded by default)
# XML
# Zip
# Crypto
# Data
# Net
# NetSSL
# OSP
#
# Usage:
# set(ENV{Poco_DIR} path/to/poco/sdk)
# find_package(Poco REQUIRED OSP Data Crypto)
#
# On completion, the script defines the following variables:
#
# - Compound variables:
# Poco_FOUND
# - true if all requested components were found.
# Poco_LIBRARIES
# - contains release (and debug if available) libraries for all requested components.
# It has the form "optimized LIB1 debug LIBd1 optimized LIB2 ...", ready for use with the target_link_libraries command.
# Poco_INCLUDE_DIRS
# - Contains include directories for all requested components.
#
# - Component variables:
# Poco_Xxx_FOUND
# - Where Xxx is the properly cased component name (eg. 'Util', 'OSP').
# True if a component's library or debug library was found successfully.
# Poco_Xxx_LIBRARY
# - Library for component Xxx.
# Poco_Xxx_LIBRARY_DEBUG
# - debug library for component Xxx
# Poco_Xxx_INCLUDE_DIR
# - include directory for component Xxx
#
# - OSP BundleCreator variables: (i.e. bundle.exe on windows, bundle on unix-likes)
# (is only discovered if OSP is a requested component)
# Poco_OSP_Bundle_EXECUTABLE_FOUND
# - true if the bundle-creator executable was found.
# Poco_OSP_Bundle_EXECUTABLE
# - the path to the bundle-creator executable.
