 # omnipython-lvgl is not a module directory: it is LVGL, its generated
 # bindings and a port per interpreter. --modules names it lvgl ("all" takes it
 # too), and a build fetches it at this commit into modules/.omnipython-lvgl (a
 # sibling checkout is linked there instead) and compiles the port for its
 # interpreter. Move the commit here to move every LVGL build, MicroPython's and
 # CircuitPython's.
