This might possibly be related to the problem described in the comment for:
https://github.com/mesonbuild/meson/pull/2880/commits/8a27c08b05e4537d5061d30ddd8aad9dc52cf1c4

I believe it's is an infelicity in meson that it doesn't echo the actual
failing command here.
Noted here:

Yeah, I wasn't expecting it to use this method of executing the command
line (storing it in a pickle and then using a python wrapper to execute
it) to be used except on Windows, so I'll have to take a more detailed
look at why that's happening.
