# - Find the Poco includes and libraries.
# The following variables are set if Poco is found.  If Poco is not
# found, Poco_FOUND is set to false.
#  Poco_FOUND        - True when the Poco include directory is found.
#  Poco_INCLUDE_DIRS - the path to where the poco include files are.
#  Poco_LIBRARY_DIRS - The path to where the poco library files are.
#  Poco_BINARY_DIRS - The path to where the poco dlls are.

# ----------------------------------------------------------------------------
# If you have installed Poco in a non-standard location.
# Then you have three options. 
# In the following comments, it is assumed that <Your Path>
# points to the root directory of the include directory of Poco. e.g
# If you have put poco in C:\development\Poco then <Your Path> is
# "C:/development/Poco" and in this directory there will be two
# directories called "include" and "lib".
# 1) After CMake runs, set Poco_INCLUDE_DIR to <Your Path>/poco<-version>
# 2) Use CMAKE_INCLUDE_PATH to set a path to <Your Path>/poco<-version>. This will allow FIND_PATH()
#    to locate Poco_INCLUDE_DIR by utilizing the PATH_SUFFIXES option. e.g.
#    SET(CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} "<Your Path>/include")
# 3) Set an environment variable called ${POCO_ROOT} that points to the root of where you have
#    installed Poco, e.g. <Your Path>. It is assumed that there is at least a subdirectory called
#    Foundation/include/Poco in this path.
#
# Note:
#  1) If you are just using the poco headers, then you do not need to use
#     Poco_LIBRARY_DIRS in your CMakeLists.txt file.
#  2) If Poco has not been installed, then when setting Poco_LIBRARY_DIRS
#     the script will look for /lib first and, if this fails, then for /stage/lib.
#
# Usage:
# In your CMakeLists.txt file do something like this:
# ...
# # Poco
# FIND_PACKAGE(Poco)
# ...
# INCLUDE_DIRECTORIES(${Poco_INCLUDE_DIRS})
# LINK_DIRECTORIES(${Poco_LIBRARY_DIRS})
#
# In Windows, we make the assumption that, if the Poco files are installed, the default directory
# will be C:\poco or C:\Program Files\Poco.
