# Try to find OpenTissue, runtime libraries, and include paths.
# Once done this will define
#
# OPENTISSUE_FOUND        : system has OpenTissue and it can be used.
# OPENTISSUE_INCLUDE_DIRS : Directories need to find header-files used by OpenTissue and OpenTissue itself
# OPENTISSUE_LIBRARY_DIRS : Directories where the compiler can find static libraries of third-party software used by OpenTissue.
# OPENTISSUE_LIBS         : Full paths to all libraries of third-party software used by OpenTissue.
# OPENTISSUE_FLAGS        : OpenTissue compiler flags that should be used for any application using OpenTissue.
#
# Typical usage is
#
# find_package(OpenTissue)
# if(OPENTISSUE_FOUND)
#  include_directories( ${OPENTISSUE_INCLUDE_DIRS} )
#  link_directories( ${OPENTISSUE_LIBRARY_DIRS} )
#  add_definitions( ${OPENTISSUE_FLAGS} )

# And for each target using OpenTissue one would have to use
#
