与节俭链接

Question

当我尝试将我的可执行文件链接到我的使用thrift的库时，我得到了undefined reference to 'typeinfo for apache::thrift::transport::TTransportException' (和其他符号)。我在Ubuntu18.04上使用了GCC 7.3.0，在CLion中用CMake构建，我花了一天的时间在谷歌上搜索这个问题，并访问了this，that和this链接。

CMake命令如下所示

对于我的共享对象：

TARGET_LINK_LIBRARIES(server INTERFACE
                      etcdclient
                      TopologyProtocols
                      event
                      ${THRIFT_LIBRARIES}
                      ${Boost_LIBRARIES}
                      lzo2
                      sqlite3
                      zmq
                      ${SPDK_LIBS}
                      ${DPDK_LIBS}
                      grpc
                      grpc++
                      gtest
                      gmock
                      xml2
                      stdc++fs
                      bfd
                      -l:libisal.so.2
                      sgutils2
                      pthread
                      uuid
                      rt
                      )

可执行的CMake命令：

TARGET_LINK_LIBRARIES(kserver
                      server
                      ${THRIFT_LIBRARIES}
                      )

CMake生成的链接器命令：

cmake_link_script CMakeFiles/kserver.dir/link.txt --verbose=1
/usr/bin/c++  -O3 -DNDEBUG   CMakeFiles/kserver.dir/main.cpp.o  -o kserver  -L/server/ext/spdk/build/lib  -L/server/ext/spdk/dpdk/build/lib  -L/server/ext/isal/lib -Wl,-rpath,/server/ext/spdk/build/lib:/server/ext/spdk/dpdk/build/lib:/server/ext/isal/lib:/server/cmake-build-release/lib/proj:/usr/local/lib:/server/cmake-build-release/ext/etcd:/server/cmake-build-release/protocols ../../lib/proj/libproj.so /usr/local/lib/libthrift.so /usr/local/lib/libthriftnb.so ../../ext/etcd/libetcdclient.so ../../protocols/libTopologyProtocols.so /home/user/vcpkg/installed/x64-linux/lib/libprotobuf.a -levent /usr/local/lib/libthrift.so /usr/local/lib/libthriftnb.so /home/user/vcpkg/installed/x64-linux/lib/libboost_system.a -llzo2 /home/user/vcpkg/installed/x64-linux/lib/libsqlite3.a -lpthread -ldl -lzmq -lspdk -ldpdk -lgrpc -lgrpc++ -lgtest -lgmock -lxml2 -lstdc++fs -lbfd -l:libisal.so.2 -lsgutils2 -lpthread -luuid -lrt

该命令看起来非常好，它与编译器和常规项目设置中的thrift、thriftnb和event链接，这里是源代码根目录中根CMakeList.txt的内容

我哪里做错了？

我花了两天的时间才发现我的机器上安装了一些深奥的版本，在手动删除它并使用vcpkg everything linked提供的版本后，包管理器并不知道它。
