# A CMake find module for the OpenSlide microscopy file reader library.

# http://openslide.org
#
# Once done, this module will define
#   OPENSLIDE_FOUND         - system has OpenSlide
#   OPENSLIDE_INCLUDE_DIRS  - the OpenSlide include directory
#   OPENSLIDE_LIBRARIES     - link to these to use OpenSlide
#   OpenSlide::OpenSlide    - imported target

# Look for the header.
