# - Find libqes
# Find the native libqes includes and library.
# Once done this will define
#
# LIBQES_INCLUDE_DIRS - where to find qes.h, etc.
# LIBQES_LIBRARIES - List of libraries when using libqes.
# LIBQES_FOUND - True if libqes found.
#
# LIBQES_VERSION_STRING - The version of libqes found (x.y.z)
# LIBQES_VERSION_MAJOR - The major version of libqes
# LIBQES_VERSION_MINOR - The minor version of libqes
# LIBQES_VERSION_PATCH - The patch version of libqes
# LIBQES_VERSION_PREREL - The pre-release version of libqes
# LIBQES_VERSION_GIT - The git version of libqes
#
# An includer may set LIBQES_ROOT to a libqes installation root to tell
# this module where to look.
