前言
很多大工程由不同动态库和程序构成，并表现为多级目录和子工程的样式。
一， 目录结构
├── CMakeLists.txt -------------------->[1]
├── subbinary
│ ├── CMakeLists.txt----------->[2]
│ └── main.cpp
├── sublibrary1
│ ├── CMakeLists.txt------------>[3]
│ ├── include
│ │ └── sublib1
│ │ └── sublib1.h
│ └── src
│ └── sublib1.cpp
└── sublibrary2
├── CMakeLists.txt------------>[4]
└── include
└── sublib2
└── sublib2.h
* link:CMakeLists.txt[] - Top level CMakeLists.txt
* link:subbinary/CMakeLists.txt[] - to make the executable
* link:subbinary/main.cpp[] - source for the executable
* link:sublibrary1/CMakeLists.txt[] - to make a static library
* link:sublibrary1/include/sublib1/sublib1.h[]
* link:sublibrary1/src/sublib2.cpp[]
* link:sublibrary2/CMakeLists.txt[] - to setup header only library
* link:sublibrary2/include/sublib2/sublib2.h[]
二，cmake脚本
├── CMakeLists.txt -------------------->[1]
cmake_minimum_required (VERSION 3.5)
project(subprojects)
# 添加子目录
add_subdirectory(sublibrary1)
add_subdirectory(sublibrary2)
add_subdirectory(subbinary)
├── CMakeLists.txt----------->[2]
project(subbinary)
# 创建可执行程序
add_executable(${PROJECT_NAME} main.cpp)
# 使用别名 sub::lib1 链接subproject1下的静态库
# 使用别名 sub::lib2 链接subproject2下的库文件
target_link_libraries(${PROJECT_NAME}
sub::lib1
sub::lib2
)
├── CMakeLists.txt------------>[3]
project (sublibrary1)
# 添加工程源文件到库，设置库别名
add_library(${PROJECT_NAME} src/sublib1.cpp)
add_library(sub::lib1 ALIAS ${PROJECT_NAME})
# 包含相关的头文件
target_include_directories( ${PROJECT_NAME}
PUBLIC ${PROJECT_SOURCE_DIR}/include
)
├── CMakeLists.txt------------>[4]
project (sublibrary2)
add_library(${PROJECT_NAME} INTERFACE)
add_library(sub::lib2 ALIAS ${PROJECT_NAME})
target_include_directories(${PROJECT_NAME}
INTERFACE
${PROJECT_SOURCE_DIR}/include
)
