Cmake 的路径设置

　　设置库文件的输出路径，dll 和 lib 的输出：

1 set(CMAKE_RUNTIME_OUTPUT_DIRECTORY_DEBUG e:/tmp/bin/debug) # 设置exe文件路径
2 set(CMAKE_RUNTIME_OUTPUT_DIRECTORY_RELEASE e:/tmp/bin/release)
3 
4 set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY_DEBUG e:/tmp/bin/debug) # 设置静态库路径
5 set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY_RELEASE e:/tmp/bin/release)

6 set(CMAKE_LIBRARY_OUTPUT_DIRECTORY_DEBUG e:/tmp/bin/debug)   # 设置lib库路径
7 set(CMAKE_LIBRARY_OUTPUT_DIRECTORY_RELEASE e:/tmp/bin/release)

　　设置exe文件的输出路径：

1 set(EXECUTABLE_OUTPUT_PATH e:/tmp/bin/debug)

　　一个极简的lib 库cmake应用例子

cmake_minimum_required(VERSION 3.14)
 
project(libtest LANGUAGES CXX)
 
set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
 
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY_DEBUG "${CMAKE_CURRENT_SOURCE_DIR}/../libtest/libd")
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY_RELEASE "${CMAKE_CURRENT_SOURCE_DIR}/../libtest/lib")
 
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY_DEBUG "${CMAKE_CURRENT_SOURCE_DIR}/../libtest/libd")
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY_RELEASE "${CMAKE_CURRENT_SOURCE_DIR}/../libtest/lib")
 
add_library(libtest SHARED
  libtest_global.h
  ibase.cpp
  ibase.h
  cbase.cpp
  cbase.h
)
 
if(CMAKE_BUILD_TYPE AND (CMAKE_BUILD_TYPE STREQUAL "Debug"))
    file(COPY ibase.h libtest_global.h DESTINATION  ${CMAKE_RUNTIME_OUTPUT_DIRECTORY_DEBUG})
else()
    file(COPY ibase.h libtest_global.h DESTIONATION  ${CMAKE_RUNTIME_OUTPUT_DIRECTORY_RELEASE})
endif()
 
target_compile_definitions(libtest PRIVATE LIBTEST_LIBRARY)

调用上述 lib 库的 cmake 例子：

cmake_minimum_required(VERSION 3.5)
 
project(uselibtest LANGUAGES CXX)
 
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
 
# 以下两种方式可选一种
#target_include_directories(${PROJECT_NAME} PUBLIC "${CMAKE_CURRENT_SOURCE_DIR}/../libtest/lib")
include_directories(${CMAKE_CURRENT_SOURCE_DIR}/../libtest/lib)
 
add_executable(${PROJECT_NAME} main.cpp)
 
#以下两种方式均可，如果没有使用全路径lib库，仅仅使用lib库名，则需要将该库copy 到 exe 执行目录下，才可以编译通过
#find_library(lib_var libtest "${CMAKE_CURRENT_SOURCE_DIR}/../libtest/lib")
#target_link_libraries(${PROJECT_NAME} ${lib_var})
target_link_libraries(${PROJECT_NAME} "${CMAKE_CURRENT_SOURCE_DIR}/../libtest/lib/libtest.lib")

使用QRPC时，总是不能顺利生成rep source端的对应文件，终于找到了bug, 问题解决。顺带说一句，qt 的说明文档里，把QTimer 的信号函数也写错了。真不走心，居然没人提示他们。是因为没有直接给出完整源码吗？哈哈

cmake_minimum_required(VERSION 3.14)
 
project(client LANGUAGES CXX)
 
set(CMAKE_INCLUDE_CURRENT_DIR ON)
 
set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
 
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
 
find_package(QT NAMES Qt6 Qt5 COMPONENTS Core RemoteObjects REQUIRED)
find_package(Qt${QT_VERSION_MAJOR} COMPONENTS Core RemoteObjects REQUIRED)
 
set(SOURCES
    main.cpp
    simpleswitch.cpp
)
 
qt5_generate_repc(SOURCES simpleswitch.rep SOURCE)
 
add_executable(client
  ${SOURCES}
)
target_link_libraries(client Qt${QT_VERSION_MAJOR}::Core Qt${QT_VERSION_MAJOR}::RemoteObjects)

RPC的副本端cmake文件，区别主要是生成repc 的参数

cmake_minimum_required(VERSION 3.14)
 
project(server LANGUAGES CXX)
 
set(CMAKE_INCLUDE_CURRENT_DIR ON)
 
set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
 
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
 
find_package(QT NAMES Qt6 Qt5 COMPONENTS Core RemoteObjects REQUIRED)
find_package(Qt${QT_VERSION_MAJOR} COMPONENTS Core RemoteObjects REQUIRED)
 
set(SOURCES
    main.cpp
    client.cpp
)
 
qt5_generate_repc(SOURCES ${CMAKE_SOURCE_DIR}/../rep/simpleswitch.rep REPLICA)
 
add_executable(server
  ${SOURCES}
)
target_link_libraries(${PROJECT_NAME} Qt${QT_VERSION_MAJOR}::Core Qt${QT_VERSION_MAJOR}::RemoteObjects)
