# Locate the Google C++ Testing Framework.
#
# Defines the following variables:
#
#   GTEST_FOUND - Found the Google Testing framework
#   GTEST_INCLUDE_DIRS - Include directories
#
# Also defines the library variables below as normal
# variables.  These contain debug/optimized keywords when
# a debugging library is found.
#
#   GTEST_BOTH_LIBRARIES - Both libgtest & libgtest-main
#   GTEST_LIBRARIES - libgtest
#   GTEST_MAIN_LIBRARIES - libgtest-main
#
# Accepts the following variables as input:
#
#   GTEST_ROOT - (as a CMake or environment variable)
#                The root directory of the gtest install prefix
#
#   GTEST_MSVC_SEARCH - If compiling with MSVC, this variable can be set to
#                       "MD" or "MT" to enable searching a GTest build tree
#                       (defaults: "MD")
#
#-----------------------
# Example Usage:
#
#    enable_testing()
#    find_package(GTest REQUIRED)
#    include_directories(${GTEST_INCLUDE_DIRS})
#
#    add_executable(foo foo.cc)
#    target_link_libraries(foo ${GTEST_BOTH_LIBRARIES})
#
#    add_test(AllTestsInFoo foo)
#
#-----------------------
#
# If you would like each Google test to show up in CTest as
# a test you may use the following macro.
# NOTE: It will slow down your tests by running an executable
# for each test and test fixture.  You will also have to rerun
# CMake after adding or removing tests or test fixtures.
#
# GTEST_ADD_TESTS(executable extra_args ARGN)
#    executable = The path to the test executable
#    extra_args = Pass a list of extra arguments to be passed to
#                 executable enclosed in quotes (or "" for none)
#    ARGN =       A list of source files to search for tests & test
#                 fixtures.
#
#  Example:
#     set(FooTestArgs --foo 1 --bar 2)
#     add_executable(FooTest FooUnitTest.cc)
#     GTEST_ADD_TESTS(FooTest "${FooTestArgs}" FooUnitTest.cc)
