# 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) #============================================================================= # Copyright 2009 Kitware, Inc. # Copyright 2009 Philip Lowman <philip@yhbt.com> # Copyright 2009 Daniel Blezek <blezek@gmail.com> # # Distributed under the OSI-approved BSD License (the "License"); # see accompanying file Copyright.txt for details. # # This software is distributed WITHOUT ANY WARRANTY; without even the # implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. # See the License for more information. #============================================================================= # (To distribute this file outside of CMake, substitute the full # License text for the above reference.) # # Thanks to Daniel Blezek <blezek@gmail.com> for the GTEST_ADD_TESTS code function(GTEST_ADD_TESTS executable extra_args) if(NOT ARGN) message(FATAL_ERROR "Missing ARGN: Read the documentation for GTEST_ADD_TESTS") endif() foreach(source ${ARGN}) file(READ "${source}" contents) string(REGEX MATCHALL "TEST_?F?\\(([A-Za-z_0-9 ,]+)\\)" found_tests ${contents}) foreach(hit ${found_tests}) string(REGEX REPLACE ".*\\( *([A-Za-z_0-9]+), *([A-Za-z_0-9]+) *\\).*" "\\1.\\2" test_name ${hit}) add_test(${test_name} ${executable} --gtest_filter=${test_name} ${extra_args}) endforeach() endforeach() endfunction() function(_gtest_append_debugs _endvar _library) if(${_library} AND ${_library}_DEBUG) set(_output optimized ${${_library}} debug ${${_library}_DEBUG}) else() set(_output ${${_library}}) endif() set(${_endvar} ${_output} PARENT_SCOPE) endfunction() function(_gtest_find_library _name) find_library(${_name} NAMES ${ARGN} HINTS ENV GTEST_ROOT ${GTEST_ROOT} PATH_SUFFIXES ${_gtest_libpath_suffixes} ) mark_as_advanced(${_name}) endfunction() # if(NOT DEFINED GTEST_MSVC_SEARCH) set(GTEST_MSVC_SEARCH MD) endif() set(_gtest_libpath_suffixes lib) if(MSVC) if(GTEST_MSVC_SEARCH STREQUAL "MD") list(APPEND _gtest_libpath_suffixes msvc/gtest-md/Debug msvc/gtest-md/Release) elseif(GTEST_MSVC_SEARCH STREQUAL "MT") list(APPEND _gtest_libpath_suffixes msvc/gtest/Debug msvc/gtest/Release) endif() endif() find_path(GTEST_INCLUDE_DIR gtest/gtest.h HINTS $ENV{GTEST_ROOT}/include ${GTEST_ROOT}/include ) mark_as_advanced(GTEST_INCLUDE_DIR) if(MSVC AND GTEST_MSVC_SEARCH STREQUAL "MD") # The provided /MD project files for Google Test add -md suffixes to the # library names. _gtest_find_library(GTEST_LIBRARY gtest-md gtest) _gtest_find_library(GTEST_LIBRARY_DEBUG gtest-mdd gtestd) _gtest_find_library(GTEST_MAIN_LIBRARY gtest_main-md gtest_main) _gtest_find_library(GTEST_MAIN_LIBRARY_DEBUG gtest_main-mdd gtest_maind) else() _gtest_find_library(GTEST_LIBRARY gtest) _gtest_find_library(GTEST_LIBRARY_DEBUG gtestd) _gtest_find_library(GTEST_MAIN_LIBRARY gtest_main) _gtest_find_library(GTEST_MAIN_LIBRARY_DEBUG gtest_maind) endif() include(${CMAKE_CURRENT_LIST_DIR}/FindPackageHandleStandardArgs.cmake) FIND_PACKAGE_HANDLE_STANDARD_ARGS(GTest DEFAULT_MSG GTEST_LIBRARY GTEST_INCLUDE_DIR GTEST_MAIN_LIBRARY) if(GTEST_FOUND) set(GTEST_INCLUDE_DIRS ${GTEST_INCLUDE_DIR}) _gtest_append_debugs(GTEST_LIBRARIES GTEST_LIBRARY) _gtest_append_debugs(GTEST_MAIN_LIBRARIES GTEST_MAIN_LIBRARY) set(GTEST_BOTH_LIBRARIES ${GTEST_LIBRARIES} ${GTEST_MAIN_LIBRARIES}) endif()
