Some bugfixes, also added public function for closer integration btwn GoogleTest & CTest, contributed by Dan Blezek.
Other minor changes: * Enhanced documentation & added examples * _INCLUDE_DIRS and _LIBRARIES was being set regardless of _FOUND * Fixed status message to include library rather than include dir * Improved detection of MSVC compiled libraries * Added a variable (GTEST_BOTH_LIBRARIES) for libgtest + libgtest_main

#
# GTEST_FOUND - Found the Google Testing framework
# GTEST_INCLUDE_DIRS - Include directories
-# GTEST_LIBRARIES - The GTest library
-# GTEST_MAIN_LIBRARIES - The GTest library for automatic main()
#
-# Accepts the following CMake/Environment variables as input:
+# Also defines the library variables below as normal
+# variables. These contain debug/optimized keywords when
+# a debugging library is found.
#
-# GTEST_ROOT - The root directory of the gtest install prefix
+# 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)
