通常链接pthread在CMake脚本中都是这样做的

在CMake脚本中链接`pthread`库,通常需要以下几个步骤:
1. **找到库**:首先,在CMakeLists.txt文件中添加对`Threads::Threads`或`pthread`的查找,这会自动处理跨平台兼容性。例如:
```cmake
find_package(Threads REQUIRED)
```
2. **包含头文件**:如果找到了`Threads`库,通常会包含对应的头文件,如`#include <thread>`。
3. **目标链接**:在`target_link_libraries()`函数中指定你的目标(比如 executable 或 library)需要链接`pthread`,例如:
```cmake
target_link_libraries(your_target Threads::Threads)
```
4. **Windows上特别说明**:在Windows平台上,链接的是`libcpthreads`或`libwinpthread`,而不是`pthread`,所以需要特别注明。
```cmake
if(WIN32)
target_link_libraries(your_target Threads::Win32)
endif()
```
记得在每个模块或项目开始处执行上述操作,并检查构建配置是否成功识别并链接了`pthread`。

cmake 链接pthread
的时候需要怎么写?
在使用CMake进行项目构建时,需要链接pthread库,可以使用以下代码:
```
find_package(Threads REQUIRED)
target_link_libraries(${PROJECT_NAME} PRIVATE Threads::Threads)
```
其中,Threads::Threads是CMake自带的pthread库别名,可以方便地使用。
cmake pthread
CMake is a cross-platform build system that helps automate the process of building software. It provides a simple syntax for describing the build process, allowing developers to specify the source files, libraries, and dependencies required to build their software.
pthread is a library for POSIX threads (threads for the Unix-like operating systems). It provides a set of functions for creating, managing, and synchronizing threads. pthread is often used in multi-threaded applications to take advantage of the multiple cores available on modern processors, improving the performance of the application.
When using CMake to build an application that uses pthread, you need to include the pthread library in your CMakeLists.txt file. This can be done by adding the following line:
target_link_libraries(your_target_name pthread)
Replace "your_target_name" with the name of your target executable. This tells CMake to link the pthread library with your application when it is built.
