[CMake] What is a utility target ?

[Craig Scott]

In the context of that particular part of the CMake documentation, it is
referring to targets that are not created by add_library() or
add_executable(). Targets created by add_custom_target() are not something
CMake knows what to do with if you give them to the target_link_libraries()
command, since these custom targets may not (and typically won't)
correspond to a physical file being created (that's what
add_custom_command() is for). So the term *utility target* can be thought
of as being a custom target you create for convenience, but not something
which actually corresponds to a library or executable. Examples of utility
targets that CMake will automatically create for you include things like
*all*, *test*, *package*, etc.
