+## CMake configuration file of gflags project
+##
+## This CMakeLists.txt defines some gflags specific configuration variables
+## using the "gflags_define" utility macro. The default values of these variables
+## can be overridden either on the CMake command-line using the -D option of
+## the cmake command or in a super-project which includes the gflags source
+## tree by setting the GFLAGS_<varname> CMake variables before adding the
+## gflags source directory via CMake's "add_subdirectory" command. Only when
+## the non-cached variable GFLAGS_IS_SUBPROJECT has a value equivalent to FALSE,
+## these configuration variables are added to the CMake cache so they can be
+## edited in the CMake GUI. By default, GFLAGS_IS_SUBPROJECT is set to TRUE when
+## the CMAKE_SOURCE_DIR is not identical to the directory of this CMakeLists.txt
+## file, i.e., the top-level directory of the gflags project source tree.
+##
+## When this project is a subproject (GFLAGS_IS_SUBPROJECT is TRUE), the default
+## settings are such that only the static single-threaded library is built without
+## installation of the gflags files. The "gflags" target is in this case an ALIAS
+## library target for the "gflags_nothreads_static" library target. Targets which
+## depend on the gflags library should link to the "gflags" library target.
+##
+## Example CMakeLists.txt of user project which requires separate gflags installation:
+## cmake_minimum_required(VERSION 2.8.12 FATAL_ERROR)
+##
+## project(Foo)
+##
+## find_package(gflags REQUIRED)
+##
+## add_executable(foo src/foo.cc)
+## target_link_libraries(foo gflags)
+##
+## Example CMakeLists.txt of user project which requires separate single-threaded static gflags installation:
+## cmake_minimum_required(VERSION 2.8.12 FATAL_ERROR)
+##
+## project(Foo)
+##
+## find_package(gflags COMPONENTS nothreads_static)
+##
+## add_executable(foo src/foo.cc)
+## target_link_libraries(foo gflags)
+##
+## Example CMakeLists.txt of super-project which contains gflags source tree:
+## cmake_minimum_required(VERSION 2.8.12 FATAL_ERROR)
+##
+## project(Foo)
+##
+## add_subdirectory(gflags)
+##
+## add_executable(foo src/foo.cc)
+## target_link_libraries(foo gflags)
+##

+## - GFLAGS_IS_A_DLL
