      "The <name> corresponds to the logical target name and must be "

      "STATIC, SHARED, or MODULE may be given to specify the type of library "
      "to be created.  "
      "STATIC libraries are archives of object files for use when linking "
      "other targets.  "
      "SHARED libraries are linked dynamically and loaded at runtime.  "
      "MODULE libraries are plugins that are not linked into other targets "
      "but may be loaded dynamically at runtime using dlopen-like "
      "functionality.  "

      "LIBRARY_OUTPUT_DIRECTORY, and RUNTIME_OUTPUT_DIRECTORY "

      "  add_library(<name> <SHARED|STATIC|MODULE> IMPORTED)\n"
      "An IMPORTED library target references a library file located "
      "outside the project.  "
      "No rules are generated to build it.  "
      "The target name has scope in the directory in which it is created "
      "and below.  "
      "It may be referenced like any target built within the project.  "
      "IMPORTED libraries are useful for convenient reference from "
      "commands like target_link_libraries.  "
      "Details about the imported library are specified by setting "
      "properties whose names begin in \"IMPORTED_\".  "
      "The most important such property is IMPORTED_LOCATION "
      "(and its per-configuration version IMPORTED_LOCATION_<CONFIG>) "
      "which specifies the location of the main library file on disk.  "
