| Subject: [PATCH] CMakeLists.txt: fix cross-compilation with |
| gRPC_BUILD_GRPC_CPP_PLUGIN=OFF |
| |
| When cross-compiling gRPC, a native version of 'grpc_cpp_plugin' is searched |
| in the environment. For most use cases, a cross version of this file is not |
| needed. |
| |
| However, when cross-building with -DgRPC_BUILD_GRPC_CPP_PLUGIN=OFF, there |
| are some build errors, for example: |
| |
| make[3]: *** No rule to make target 'grpc_cpp_plugin', needed by 'gens/src/proto/grpc/reflection/v1alpha/reflection.grpc.pb.cc'. Stop. |
| |
| This is because there is still a hard dependency on 'grpc_cpp_plugin' for |
| these targets, not taking into account the cross-compilation case. |
| |
| Fix by depending on the variable gRPC_CPP_PLUGIN, which is set correctly for |
| either cross or native case. |
