RuntimeLibrary mismatch error when importing Protobuf (Win64, CMake)

Question

I have a project whose architecture is as follows:

├── 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

The projects directory contains all my projects (obviously):

• service is the executable project
• io a static library, in which I want to only edit the ".proto" files
• The other projects are some shared libraries basically

The third_party/protobuf contains all the protobuf installed files listed here. Note that, to install protobuf, I followed all the instructions here (using Visual Studio for Compilation and Installation, in both Debug x64 and Release x64).

The CMakeLists.txt are as follows:

./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
)

Now cmake build the solution ok, and what I'm just trying to do is just something like:

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

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

But when I try to compile I get a lot of LNK2038 and LNK2005 errors:

I found this SO question in the first place but I can't see how to do what's answered it with cmake..

Answer 1

Ok so as always I needed to ask the question for an issue blocking me for hours to find the solution by myself only minutes after...

The answer is here. 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 ../..
