incdir = include_directories(dirname)
After this incdir will contain both the current source dir as well as the
corresponding build dir. It can then be used in any subdirectory and
Meson will take care of all the busywork to make paths work.
Dirname can even be '.' to mark the current directory. Though you should
remember that the current source and build directories are always
put in the include directories by default so you only need to do
include_directories('.') if you intend to use the result in a
different subdirectory.

external dependencies being installed within your source

Instead of poking directly at the internals the subproject should be executed and
it should set a variable that the caller can then use. Something like:
