How to link google protobuf libraries via cmake on linux?
提问by cnd
I'm trying to make it same way I made it for boost :
我正在尝试以与 boost 相同的方式制作它：
find_package(Boost COMPONENTS system filesystem REQUIRED)
find_package(ProtocolBuffers)
## Compiler flags
if(CMAKE_COMPILER_IS_GNUCXX)
set(CMAKE_CXX_FLAGS "-O2")
set(CMAKE_EXE_LINKER_FLAGS "-lsqlite3 -lrt -lpthread")
endif()
target_link_libraries(complex
${Boost_FILESYSTEM_LIBRARY}
${Boost_SYSTEM_LIBRARY}
${PROTOBUF_LIBRARY}
)
(googled it somewhere) but got bad output:
（在某处用谷歌搜索）但输出不好：
CMake Warning at complex/CMakeLists.txt:18 (find_package):
Could not find module FindProtocolBuffers.cmake or a configuration file for
package ProtocolBuffers.
Adjust CMAKE_MODULE_PATH to find FindProtocolBuffers.cmake or set
ProtocolBuffers_DIR to the directory containing a CMake configuration file
for ProtocolBuffers. The file will have one of the following names:
ProtocolBuffersConfig.cmake
protocolbuffers-config.cmake
How can I link it with cmake? or maybe I even can compile .proto file using cmake?
如何将其与 cmake 链接？或者我什至可以使用 cmake 编译 .proto 文件？

You could try CMake's FindProtobufmodule:
你可以试试 CMake 的FindProtobuf模块：
include(FindProtobuf)
find_package(Protobuf REQUIRED)
include_directories(${PROTOBUF_INCLUDE_DIR})
...
target_link_libraries(complex
${Boost_FILESYSTEM_LIBRARY}
${Boost_SYSTEM_LIBRARY}
${PROTOBUF_LIBRARY}
)
For further info, run
有关更多信息，请运行
cmake --help-module FindProtobuf
