# 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 CMake or env. variable)
# The root directory of the gtest install prefix
#
# GTEST_MSVC_SEARCH - If on MSVC, enables searching the build tree of
# GTest if set to MD or MT (defaults: MD)
#
#-----------------------
# Example Usage:
#
# enable_testing(true)
# find_package(GTest REQUIRED)
# include_directories(${GTEST_INCLUDE_DIRS})
#
# add_executable(foo foo.cc)
# target_link_libraries(foo ${GTEST_BOTH_LIBRARIES})
#
# add_test(AllTestsInFoo foo)
#
#-----------------------
#
# If you would like each Google test to show up in CTest as
# a test you may use the following macro. NOTE: It WILL slow
# down your tests, so be warned.
#
# GTEST_ADD_TESTS(executable extra_args ARGN)
# executable = The path to the test executable
# extra_args = Pass a list of extra arguments to be passed to
# executable enclosed in quotes (or "" for none)
# ARGN = A list of source files to search for tests & test
# fixtures.
#
# Example:
# set(FooTestArgs --foo 1 --bar 2)
# add_executable(FooTest FooUnitTest.cc)
# GTEST_ADD_TESTS(FooTest "${FooTestArgs}" FooUnitTest.cc)
