Yet another option I've just learned, but...
What is the difference between using headers-only library by specifying
this requirement using <source> and <dependency>?
The manual says:
"(...)a dependency on the target (...) (so it will be brought up-to-date
whenever the target being declared is). The dependency is not used in
any other way."
What does bringing up-to-date mean for headers-only?
Also, the "not used in any other way" suggests to me that it does not
implicitly update <include> directories.
