Argument naming for the same feature for different functions.

[dememax]

Why do different meson functions like executable() and test() have the same arguments (such as dependencies) with different names (e.g., dependencies vs depends)?

[eli-schwartz]

• Dependencies are libraries and headers that are needed for compiling and linking.
• Depends are build ordering rules (A has to be built before B).

The former can sometimes imply the latter, if a library is also a target which is built rather than being looked up on the system.
