导入 Protobuf 时出现 RuntimeLibrary 不匹配错误（Win64、CMake）

Question

我有一个项目，架构如下：

├── CMakeLists.txt
├── projects
│   ├── CMakeLists.txt
│   ├── io
│   │   ├── CMakeLists.txt
│   │   ├── data.proto
│   │   └── generated
│   │       ├── data.pb.cc
│   │       └── data.pb.h
│   ├── service
│   │   ├── CMakeLists.txt
│   │   └── main.cpp
│   ├── dll_project_1
│   └── dll_project_2
└── third_party
    └── protobuf
        ├── bin
        ├── cmake
        ├── include
        └── lib

projects 目录包含我所有的项目（显然）：

service是可执行项目
io 一个静态库，我只想在其中编辑“.proto”文件
其他项目基本都是一些共享库

third_party/protobuf 包含列出的所有 protobuf 安装文件 here. Note that, to install protobuf, I followed all the instructions here（使用 Visual Studio 进行编译和安装，在 Debug x64 和发布 x64).

CMakeLists.txt如下：

./CMakeLists.txt

set(THIRD_PARTY ${CMAKE_CURRENT_SOURCE_DIR}/third_party)
set(PROTOBUF ${THIRD_PARTY}/protobuf)

set(Protobuf_USE_STATIC_LIBS ON)

include(${PROTOBUF}/cmake/protobuf-config.cmake)
include(${PROTOBUF}/cmake/protobuf-module.cmake)
include(${PROTOBUF}/cmake/protobuf-options.cmake)
include(${PROTOBUF}/cmake/protobuf-targets.cmake)

find_package(Protobuf REQUIRED HINTS ${PROTOBUF})
include_directories(${Protobuf_INCLUDE_DIRS})
link_libraries(${Protobuf_LIBRARIES})

./projects/CMakeLists.txt

add_subdirectory(io)
add_subdirectory(dll_project_1)
add_subdirectory(dll_project_2)

add_subdirectory(service)

./projects/io/CMakeLists.txt

set(PROTO
    data.proto
)

set(PROTO_GENERATED
    generated/data.pb.cc
    generated/data.pb.h
)

source_group(Proto FILES ${PROTO})
source_group(Generated FILES ${PROTO_GENERATED})

add_library(IO STATIC ${PROTO} ${PROTO_GENERATED})

./projects/service/CMakeLists.txt

add_executable(Service main.cpp)

target_link_libraries(Service
    IO
    Dll1
    Dll2
)

现在 cmake 可以构建解决方案，而我只是想做的是：

#include "../io/generated/data.pb.h"

int main()
{
    Data::SomeData d;
    d.set_value(0.0);
}

但是当我尝试编译时，出现了很多 LNK2038 和 LNK2005 错误：

我首先找到了 this SO question，但我看不到如何做用 cmake 回答的问题..

Answer 1

好吧，一如既往，我需要问一个问题，让我在几个小时后才能自己找到解决方案...

答案是. Just needed to add -Dprotobuf_MSVC_STATIC_RUNTIME=OFF in the cmake command to build the solution (this step):

cmake -G "Visual Studio 16 2019" -Dprotobuf_MSVC_STATIC_RUNTIME=OFF -DCMAKE_INSTALL_PREFIX=../../../install ../..
