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_ 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.
