I don't use this feature from the grpc package, only linking against the

Yes the cmake file is found but not the grpc_cpp_plugin.
This is due to cmake looking for the grpc_cpp_plugin in the target
sysroot instead of the native/host sysroot.
$ ls -l ./tmp/work/*/*/*/recipe-sysroot/usr/lib/cmake/grpc/*.cmake
Or use recipe-sysroot-native depending on the consuming recipe.
Just a wild guess here - does your recipe put 'grpc' into DEPENDS or
RDEPENDS, etc.
In my recipe I put 'grpc' and 'grpc-native' into DEPENDS using
PACKAGECONFIG
PACKAGECONFIG[grpc] = "-DCONFIG_GRPC=ON,-DCONFIG_GRPC=OFF,grpc
grpc-native"
Also, do you inherit cmake in your recipe?
Yes i am indeed inheriting cmake and also systemd in my recipe
It seems to me
that it's more about how to use cmake files in a recipe, as the
particularly mentioned files are packaged and pulled in a consuming
recipe.
When I look in the files packaged the cmake file is indeed here.
The issue is coming from the gRPCTargets.cmake
(https://pastebin.com/bZay7cew)
Line 159:
# Create imported target gRPC::grpc_cpp_plugin
add_executable(gRPC::grpc_cpp_plugin IMPORTED)
[snip]
The executables seem only be useful for dev and thus only as native. At
this point it seems it's about going deep into debugging your recipe, as
seems there's no solution laying on the surface.
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
The cmake package only works if you install the binaries but yocto
doesn't install binaries for the target because otherwise cmake couldn't
find the native binaries.
