# - Derived from the FindTiff.cmake and FindJPEG.cmake that is included with cmake
# FindMFU

# Find the native MFU includes and library

# Imported targets
##################

# This module defines the following :prop_tgt:`IMPORTED` targets:
#
# MFU::MFU
#  The MFU library, if found.
#
# Result variables
###################

# This module will set the following variables in your project:

#  MFU_FOUND, true if the MFU headers and libraries were found.
#  MFU_INCLUDE_DIR, the directory containing the MFU headers.
#  MFU_INCLUDE_DIRS, the directory containing the MFU headers.
#  MFU_LIBRARIES, libraries to link against to use MFU.

# Cache variables
#################

# The following variables may also be set:

#  MFU_LIBRARY, where to find the MFU library.
# message (STATUS "Finding MFU library and headers..." )
