CMake 支持大写、小写、混合大小写的命令。
|
||
|
||
## 最小版本号
|
||
|
||
```cpp
|
||
cmake_minimum_required(VERSION 2.8)
|
||
```
|
||
|
||
## 工程名
|
||
|
||
```cpp
|
||
project(<Project Name>)
|
||
```
|
||
|
||
## Include 路径
|
||
|
||
*需要出现在 add_executable 和 add_library 等之前。*
|
||
|
||
```cpp
|
||
include_directories(
|
||
<Path1>
|
||
<Path2>
|
||
...
|
||
<PathN>
|
||
)
|
||
```
|
||
|
||
## 添加库路径
|
||
|
||
*需要出现在 add_executable 和 add_library 等之前。*
|
||
|
||
```cpp
|
||
link_directories(
|
||
<Path1>
|
||
<Path2>
|
||
...
|
||
<PathN>
|
||
)
|
||
```
|
||
|
||
## 添加库文件
|
||
|
||
*已经被废弃了，需要出现在 add_executable 和 add_library 等之前。*
|
||
|
||
```cpp
|
||
link_libraries(
|
||
<Library1>
|
||
<Library2>
|
||
...
|
||
<LibraryN>
|
||
)
|
||
```
|
||
|
||
支持直接全路径的写法。
|
||
|
||
## 可执行文件目标和源码
|
||
|
||
```cpp
|
||
add_executable(
|
||
<Executable Name>
|
||
<Source1>
|
||
<Source2>
|
||
...
|
||
<SourceN>
|
||
)
|
||
```
|
||
|
||
## 库文件目标和源码
|
||
|
||
```cpp
|
||
add_library(
|
||
<Library>
|
||
<SHARED/STATIC>
|
||
<Source1>
|
||
<Source2>
|
||
...
|
||
<SourceN>
|
||
)
|
||
```
|
||
|
||
## 为目标添加库文件
|
||
|
||
*可添加的动态库或静态库，可以在 add_executable 和 add_library 等之后。*
|
||
|
||
```cpp
|
||
target_link_libraries(
|
||
<Target Name>
|
||
<Library1>
|
||
<Library2>
|
||
...
|
||
<LibraryN>
|
||
)
|
||
```
|
||
|
||
## 添加依赖工程
|
||
|
||
```cpp
|
||
add_dependencies(
|
||
<Target Name>
|
||
<Depend Target1>
|
||
<Depend Target2>
|
||
...
|
||
<Depend TargetN>
|
||
)
|
||
```
