cmake add_subdirectory 编译会导致grpc出错

[wellcomez]

我很难描述
问题是用到了grpc库
编译后运行
ERROR: Something is wrong with flag 'grpc_experiments' in file 'home/z/dev/grpc/src/core/lib/config/config_vars.cc'. One possibility: file 'home/z/dev/grpc/src/core/lib/config/config_vars.cc' is being linked both statically and dynamically into this executable. e.g. some files listed as srcs to a test and also listed as srcs of some shared lib deps of the same test.

但是如果独立编译gmssl，装到系统目录再链接没有问题
