This is a knowing issue and I have try to fix grpc but yocto is not a
platform grpc officially support:
https://github.com/grpc/grpc/pull/22498
thanks for chiming in, Stefan. So this is a known issue and upstream has
refused the patch.
his patch makes sense to me
Can't we include it in meta-oe ?
I will apply it locally anyway.
Clément, is it so far confirmed that your issue is fixed by teh patch?
I could note from my side, that carrying a patch to CMake scripts in
general is a pain, as the syntax is not very patch friendly. For GRPC -
the CMake script is also huge. But also, i've no use for the pattern so
couldn't tell how urgent this scenario would be.
Thanks
Anatol
