1 ## CMake configuration file of gflags project
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.
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.
21 ## Example CMakeLists.txt of user project which requires separate gflags installation:
22 ## cmake_minimum_required(VERSION 2.8.12 FATAL_ERROR)
26 ## find_package(gflags REQUIRED)
28 ## add_executable(foo src/foo.cc)
29 ## target_link_libraries(foo gflags)
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)
36 ## find_package(gflags COMPONENTS nothreads_static)
38 ## add_executable(foo src/foo.cc)
39 ## target_link_libraries(foo gflags)
41 ## Example CMakeLists.txt of super-project which contains gflags source tree:
42 ## cmake_minimum_required(VERSION 2.8.12 FATAL_ERROR)
46 ## add_subdirectory(gflags)
48 ## add_executable(foo src/foo.cc)
49 ## target_link_libraries(foo gflags)
51 ## Variables to configure the source files:
54 ## - GFLAGS_ATTRIBUTE_UNUSED
55 ## - GFLAGS_INTTYPES_FORMAT
57 ## Variables to configure the build:
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
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
