#.rst:
# FindQhull
# --------
#
# Try to find QHULL library and headers. This module supports both old released versions
# of QHULL ≤ 7.3.2 and newer development versions that ship with a modern config file,
# but its limited to only the reentrant version of Qhull.
#
# PCL_QHULL_REQUIRED_TYPE can be used to select if you want static or shared libraries, but it defaults to "don't care".
#
# IMPORTED Targets
# ^^^^^^^^^^^^^^^^
#
# This module defines the :prop_tgt:`IMPORTED` targets:
#
# ``QHULL::QHULL``
# Defined if the system has QHULL.
#
# Result Variables
# ^^^^^^^^^^^^^^^^
#
# This module sets the following variables:
#
# ::
#
# QHULL_FOUND True in case QHULL is found, otherwise false
#
# Example usage
# ^^^^^^^^^^^^^
#
# ::
#
# find_package(QHULL REQUIRED)
#
# add_executable(foo foo.cc)
# target_link_libraries(foo QHULL::QHULL)
#
# Skip if QHULL::QHULL is already defined
if(TARGET QHULL::QHULL)
return()
endif()
