#Copied from cmake-2.8 because we want to find the static library on Windows
# - Find zlib
# Find the native ZLIB includes and library.
# Once done this will define
#
# ZLIB_INCLUDE_DIRS - where to find zlib.h, etc.
# ZLIB_LIBRARIES - List of libraries when using zlib.
# ZLIB_FOUND - True if zlib found.
#
# ZLIB_VERSION_STRING - The version of zlib found (x.y.z)
# ZLIB_VERSION_MAJOR - The major version of zlib
# ZLIB_VERSION_MINOR - The minor version of zlib
# ZLIB_VERSION_PATCH - The patch version of zlib
# ZLIB_VERSION_TWEAK - The tweak version of zlib
#
# The following variable are provided for backward compatibility
#
# ZLIB_MAJOR_VERSION - The major version of zlib
# ZLIB_MINOR_VERSION - The minor version of zlib
# ZLIB_PATCH_VERSION - The patch version of zlib
