1. Environment
- Windows 10
- GeForce RTX 3060
- Cuda 12.1.66
- Visual Studio 2019
2. Problem
我用的是https://github.com/AlexeyAB/darknet 中 的build.ps1进行构建的，在仓库的readme文件中也推荐使用powershell 进行构建，但是构建过程中遇到了这个问题 Could NOT find PThreads4W (missing: PThreads4W_LIBRARY)

-- Could NOT find PThreads4W (missing: PThreads4W_LIBRARY) 怎么才能得到这个PThreads4W ? 或者如何解决这个问题？
3.CMakeLists.txt文件内容
if(MSVC)
target_link_libraries(darknet PRIVATE PThreads4W::PThreads4W)
target_link_libraries(darknet PRIVATE wsock32)
target_link_libraries(dark PUBLIC PThreads4W::PThreads4W)
target_link_libraries(dark PUBLIC wsock32)
target_link_libraries(uselib PRIVATE PThreads4W::PThreads4W)
target_compile_definitions(darknet PRIVATE -D_CRT_RAND_S -DNOMINMAX -D_USE_MATH_DEFINES)
target_compile_definitions(dark PRIVATE -D_CRT_RAND_S -DNOMINMAX -D_USE_MATH_DEFINES)
target_compile_definitions(dark PUBLIC -D_CRT_SECURE_NO_WARNINGS)
target_compile_definitions(uselib PRIVATE -D_CRT_RAND_S -DNOMINMAX -D_USE_MATH_DEFINES)
endif()
不知道这个PThreads4W_LIBRARY怎么整？

PThreads4W是Windows下用于多线程编程的库，似乎在您的系统中缺少或没有正确安装。为了解决这个问题，您可以尝试以下步骤：
安装PThreads4W库：
您可以从以下链接下载PThreads4W库：https://www.sourceware.org/pthreads-win32/，并在您的系统上安装它。安装后，请确保该库已正确安装，其头文件和库文件可在搜索路径中找到。
将PThreads4W添加到系统路径：
如果您已在系统上安装了PThreads4W库，则可能需要将包含PThreads4W.dll文件的目录添加到系统路径中。您可以按照以下步骤操作：
a. 打开控制面板并单击“系统”。
b. 单击“高级系统设置”。
c. 单击“环境变量”。
d. 在“系统变量”部分中，找到“Path”变量并单击“编辑”。
e. 在变量值字段的末尾添加PThreads4W.dll文件的路径（例如C：\ pthreads \ bin），用分号（;）分隔。
f. 单击“确定”关闭所有窗口。
在CMakeLists.txt中设置PThreads4W_LIBRARY变量：
在您的CMakeLists.txt文件中，您可以尝试将PThreads4W_LIBRARY变量设置为PThreads4W库文件的路径。例如：
set（PThreads4W_LIBRARY“C：/ pthreads / lib / pthreadsVC2.lib”）
请确保使用实际在您的系统上找到库文件的路径替换此路径。
应用这些更改后，尝试再次构建项目，看是否解决了问题。
