I managed to get to the bottom of this. It's a racing issue. Basically, with
MAKE_PARALLEL high enough, the

add_library(EGL ${SHARED} ${EGL_SOURCE})

in git/interface/khronos/CMakeLists.txt gets to run before the header is
generated. No dependency configured for that. And in the sources of EGL there
is egl_wayland.c which includes the generated header by the call:

wayland_add_protocol_server(
       EGL_SOURCE
       ../../interface/wayland/dispmanx.xml
       dispmanx
)

Any idea how to define this dependency? What is the value of your PARALLEL_MAKE
?
