我有一个项目，其架构如下:
├── CMakeLists.txt
├── projects
│ ├── CMakeLists.txt
│ ├── io
│ │ ├── CMakeLists.txt
│ │ ├── data.proto
│ │ └── generated
│ │ ├── data.pb.cc

│ ├── service

│ │ └── main.cpp
│ ├── dll_project_1
│ └── dll_project_2
└── third_party
└── protobuf
├── bin
├── cmake
├── include
└── lib
项目目录包含我所有的项目(显然):
服务- 为可执行项目
- io一个静态库，我只想在其中编辑".proto"文件
- 其他项目是一些共享库基本上
third_party/protobuf包含这里列出的所有protobuf安装文件。请注意，为了安装protobuf，我遵循了这里的所有说明(在Debug x64和Release x64中使用Visual Studio for Compilation and Installation)。
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})
。/项目/CMakeLists.txt
add_subdirectory(io)
add_subdirectory(dll_project_1)
add_subdirectory(dll_project_2)
add_subdirectory(service)
。/项目/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})
。/项目/服务/CMakeLists.txt
add_executable(Service main.cpp)
target_link_libraries(Service
IO
Dll1
Dll2
)
现在构建解决方案，我要做的就是像这样:
#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，我得到了很多LNK2038和LNK2005错误:

我首先发现了这个问题，但是我不知道如何用cmake来回答这个问题。
像往常一样，我需要问一个困扰我几个小时的问题，然后在几分钟后自己找到解决方案。
答案在这里。只需要在cmake命令中添加-Dprotobuf_MSVC_STATIC_RUNTIME=OFF来构建解决方案(这一步):
cmake -G "Visual Studio 16 2019" -Dprotobuf_MSVC_STATIC_RUNTIME=OFF -DCMAKE_INSTALL_PREFIX=../../../install ../..
