github.com/igggame/nebulas-go@v2.1.0+incompatible/nbre/3rd_party/build_option_bak/CMakeLists.txt-gflags (about) 1 ## CMake configuration file of gflags project 2 ## 3 ## This CMakeLists.txt defines some gflags specific configuration variables 4 ## using the "gflags_define" utility macro. The default values of these variables 5 ## can be overridden either on the CMake command-line using the -D option of 6 ## the cmake command or in a super-project which includes the gflags source 7 ## tree by setting the GFLAGS_<varname> CMake variables before adding the 8 ## gflags source directory via CMake's "add_subdirectory" command. Only when 9 ## the non-cached variable GFLAGS_IS_SUBPROJECT has a value equivalent to FALSE, 10 ## these configuration variables are added to the CMake cache so they can be 11 ## edited in the CMake GUI. By default, GFLAGS_IS_SUBPROJECT is set to TRUE when 12 ## the CMAKE_SOURCE_DIR is not identical to the directory of this CMakeLists.txt 13 ## file, i.e., the top-level directory of the gflags project source tree. 14 ## 15 ## When this project is a subproject (GFLAGS_IS_SUBPROJECT is TRUE), the default 16 ## settings are such that only the static single-threaded library is built without 17 ## installation of the gflags files. The "gflags" target is in this case an ALIAS 18 ## library target for the "gflags_nothreads_static" library target. Targets which 19 ## depend on the gflags library should link to the "gflags" library target. 20 ## 21 ## Example CMakeLists.txt of user project which requires separate gflags installation: 22 ## cmake_minimum_required(VERSION 2.8.12 FATAL_ERROR) 23 ## 24 ## project(Foo) 25 ## 26 ## find_package(gflags REQUIRED) 27 ## 28 ## add_executable(foo src/foo.cc) 29 ## target_link_libraries(foo gflags) 30 ## 31 ## Example CMakeLists.txt of user project which requires separate single-threaded static gflags installation: 32 ## cmake_minimum_required(VERSION 2.8.12 FATAL_ERROR) 33 ## 34 ## project(Foo) 35 ## 36 ## find_package(gflags COMPONENTS nothreads_static) 37 ## 38 ## add_executable(foo src/foo.cc) 39 ## target_link_libraries(foo gflags) 40 ## 41 ## Example CMakeLists.txt of super-project which contains gflags source tree: 42 ## cmake_minimum_required(VERSION 2.8.12 FATAL_ERROR) 43 ## 44 ## project(Foo) 45 ## 46 ## add_subdirectory(gflags) 47 ## 48 ## add_executable(foo src/foo.cc) 49 ## target_link_libraries(foo gflags) 50 ## 51 ## Variables to configure the source files: 52 ## - GFLAGS_IS_A_DLL 53 ## - GFLAGS_NAMESPACE 54 ## - GFLAGS_ATTRIBUTE_UNUSED 55 ## - GFLAGS_INTTYPES_FORMAT 56 ## 57 ## Variables to configure the build: 58 ## - GFLAGS_SOVERSION 59 ## - GFLAGS_BUILD_SHARED_LIBS 60 ## - GFLAGS_BUILD_STATIC_LIBS 61 ## - GFLAGS_BUILD_gflags_LIB 62 ## - GFLAGS_BUILD_gflags_nothreads_LIB 63 ## - GFLAGS_BUILD_TESTING 64 ## - GFLAGS_BUILD_PACKAGING 65 ## 66 ## Variables to configure the installation: 67 ## - GFLAGS_INCLUDE_DIR 68 ## - GFLAGS_LIBRARY_INSTALL_DIR or LIB_INSTALL_DIR or LIB_SUFFIX 69 ## - GFLAGS_INSTALL_HEADERS 70 ## - GFLAGS_INSTALL_SHARED_LIBS 71 ## - GFLAGS_INSTALL_STATIC_LIBS 72 73 cmake_minimum_required (VERSION 2.8.12 FATAL_ERROR) 74 75 if (POLICY CMP0042) 76 cmake_policy (SET CMP0042 NEW) 77 endif () 78 79 add_definitions(-stdlib=libc++) 80 # ---------------------------------------------------------------------------- 81 # includes 82 include ("${CMAKE_CURRENT_SOURCE_DIR}/cmake/utils.cmake") 83 84 # ---------------------------------------------------------------------------- 85 # package information 86 set (PACKAGE_NAME "gflags") 87 set (PACKAGE_VERSION "2.2.1") 88 set (PACKAGE_STRING "${PACKAGE_NAME} ${PACKAGE_VERSION}") 89 set (PACKAGE_TARNAME "${PACKAGE_NAME}-${PACKAGE_VERSION}") 90 set (PACKAGE_BUGREPORT "https://github.com/gflags/gflags/issues") 91 set (PACKAGE_DESCRIPTION "A commandline flags library that allows for distributed flags.") 92 set (PACKAGE_URL "http://gflags.github.io/gflags") 93 94 project (${PACKAGE_NAME} CXX) 95 if (CMAKE_VERSION VERSION_LESS 3.4) 96 # C language still needed because the following required CMake modules 97 # (or their dependencies, respectively) are not correctly handling 98 # the case where only CXX is enabled 99 # - CheckTypeSize.cmake (fixed in CMake 3.1, cf. https://cmake.org/Bug/view.php?id=14056) 100 # - FindThreads.cmake (fixed in CMake 3.4, cf. https://cmake.org/Bug/view.php?id=14905) 101 enable_language (C) 102 endif () 103 104 version_numbers ( 105 ${PACKAGE_VERSION} 106 PACKAGE_VERSION_MAJOR 107 PACKAGE_VERSION_MINOR 108 PACKAGE_VERSION_PATCH 109 ) 110 111 # shared library ABI version number, can be overridden by package maintainers 112 # using -DGFLAGS_SOVERSION=XXX on the command-line 113 if (GFLAGS_SOVERSION) 114 set (PACKAGE_SOVERSION "${GFLAGS_SOVERSION}") 115 else () 116 # TODO: Change default SOVERSION back to PACKAGE_VERSION_MAJOR with the 117 # next increase of major version number (i.e., 3.0.0 -> SOVERSION 3) 118 # The <major>.<minor> SOVERSION should be used for the 2.x releases 119 # versions only which temporarily broke the API by changing the default 120 # namespace from "google" to "gflags". 121 set (PACKAGE_SOVERSION "${PACKAGE_VERSION_MAJOR}.${PACKAGE_VERSION_MINOR}") 122 endif () 123 124 # when gflags is included as subproject (e.g., as Git submodule/subtree) in the source 125 # tree of a project that uses it, no variables should be added to the CMake cache;
