# - Try to find Judy.
#
# Additionally, on Windows, this module reads hints about search locations from variables:
#  JUDY_ROOT             - Preferred installation prefix
#
# To build Judy on Windows: (Tested with judy-1.0.5)
#
# * Download the sources tarball from http://sourceforge.net/projects/judy/
# * Extract the source
# * Win32: open the Visual Studio C++ Express 2010 command prompt and navigate to the src/ directory.
#   Then execute:  build.bat
#	* Win64: open the Windows SDK 7.1 Command Prompt and navigate to the src/ directory
#   Then execute:  build.bat
# * Run the mariadb build with JUDY_ROOT=path\to\judy
#
# Once done this will define
#
#  Judy_FOUND - system has Judy
#  Judy_INCLUDE_DIRS - the Judy include directory
#  Judy_LIBRARIES - Link these to use Judy
#  Judy_DEFINITIONS - Compiler switches required for using Judy
