OpenCV 作为静态库（cmake 选项）
我想在嵌入式系统中使用 OpenCV 库，并且需要使用 OpenCV 作为静态库来编译我的项目。
如何使用 cmake 选项创建库？

How can I create the library using cmake options ?

要将 OpenCV 构建为静态库，您需要将 BUILD_SHARED_LIBS 标志设置为 false/off：
但我认为这对于您的任务来说还不够，因为您实际上需要为您的架构交叉编译库。如果是 Android 或 IOS，这样的端口已经存在，您可以简单地使用它。如果是其他平台，您需要创建自己的 cmake 工具链文件以进行交叉编译，并可能在 OpenCV 构建系统中进行一些修复。
To build OpenCV as static library you need to set
BUILD_SHARED_LIBSflag to false/off:But I think it is not enough for your task because you actually need to cross-compile library for you architecture. In case of Android or IOS such port already exists and you can simply use it. In case of another platform you need to create your own cmake toolchain file for cross-compiling and probably make a number of fixes in OpenCV build system.
BUILD_SHARED_LIBS=OFFcmake 选项将创建静态库。应该注意的是，在撰写本文时，OpenCV 并不真正支持静态构建，因为安装在某个地方时结果将无法使用。

The
BUILD_SHARED_LIBS=OFFcmake option will create static libraries.It should be noted that at the time of writing this, OpenCV does not really support static build, in that the result will not be useable when installed somewhere.
