To make the names consistent, the best way is to write the name in only
one place, i.e. in meson itself or a meson function/macro. Not in each
individual modules.
Like the GTK_DOC_CHECK Autotools macro.
The same for compiler flags, with the Autotools there is the
AX_COMPILER_FLAGS macro. With meson it seems that the flags are listed
in each GNOME module.
