我有一个 .bat，用于在运行一些程序之前设置一些环境变量。

我想永久设置这些环境变量，但如果可能的话，我不想手动进行。这里有捷径吗？有没有我可以设置永久添加到 PATH 的标志？

代码来自于 OpenVino 提供的 setupvars.bat ：

set ROOT=%~dp0
call :GetFullPath "%ROOT%\.." ROOT
set SCRIPT_NAME=%~nx0

set "INTEL_OPENVINO_DIR=%ROOT%"
set "INTEL_CVSDK_DIR=%INTEL_OPENVINO_DIR%"

where /q libmmd.dll || echo Warning: libmmd.dll couldn't be found in %%PATH%%. Please check if the redistributable package for Intel(R) C++ Compiler is installed and the library path is added to the PATH environment variable. System reboot can be required to update the system environment.

对于 OpenVINO，每次打开命令行时都需要运行 setupvars.sh 脚本。但是，您也可以将所需的所有变量添加到系统环境变量中。

在 Windows® 10 系统上，转到控制面板 > 系统和安全 > 系统 > 高级系统设置 > 环境变量。

有关所需变量及其值的列表，请参阅此文档。
