Commit 903de16f5f added passing
'--with-libgrpc++' with the explanation:
"Use --with-libgrpc++ option as otherwise collectd will try to find
grpc++.pc which is not available."
At the time of above commit, grpc version in Buildroot was 1.23.0.
Since grpc 1.25.0, a grpc++.pc file _is_ generated from cmake builds.
Hence, remove passing --with-libgrpc++.
This change fixes a problem introduced by commit
fedf3318e3. As a side effect of that change, a
target version of 'grpc_cpp_plugin' was now created. When collectd was built
after grpc, even without grpc support in collectd enabled, the collectd
configure script would find this target grpc_cpp_plugin and try to use it
(which is not possible because it is built for target).
When not passing '--with-libgrpc++', collectd will instead find the host
version of grpc_cpp_plugin, which works fine.
There are still two underlying problems:
1. the target version of grpc_cpp_plugin is not actually needed. This will
be disabled in a subsequent commit.
2. collectd should not execute any grpc-related action if grpc support for
collectd is disabled. This problem has been reported upstream:
