# FindGTest
# ---------
#
# Locate GUnit C++ Testing Framework
#
# Imported targets
# ^^^^^^^^^^^^^^^^
#
# This module defines the following :prop_tgt:`IMPORTED` targets:
#
# ``GUnit::GUnit``
# The GUnit if found; adds GTest::GTest automatically
#
# ``GUnit::Main``
# Wraps GTest::Main
#
#
# Result variables
# ^^^^^^^^^^^^^^^^
#
# This module will set the following variables in your project:
#
# ``GUNIT_FOUND``
#   Found the GUnit framework
# ``GUNIT_INCLUDE_DIRS``
#   the directory containing the GUnit headers
#
#
# Cache variables
# ^^^^^^^^^^^^^^^
#
# The following cache variables may also be set:
#
# ``GUNIT_ROOT``
#   The root directory of the GUnit installation (may also be
#   set as an environment variable)
#
#
# Example usage
# ^^^^^^^^^^^^^
#
# ::
#
#     find_package(GUnit REQUIRED)
#
#     add_executable(foo foo.cc)
#     target_link_libraries(foo GUnit::GUnit GUnit::Main)
