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)
