CMake 找不到 Visual Studio、openvino 的任何实例答案

【问题标题】：CMake could not find any instance of Visual Studio, openvinoCMake 找不到 Visual Studio、openvino 的任何实例

【问题描述】：

由于我的 cpu 中没有 avx 指令，我使用了复制 cpu_extensionavx2.dll

移除 avx2 并复制到 build 文件夹中

我已经使用以下命令运行了 setupvars.bat：

"C:\Program Files (x86)\IntelSWTools\openvino\bin\setupvars.bat"

它正在工作。

在运行cmake 时，通过运行以下命令：

"C:\Program Files\CMake\bin\cmake.exe" ^
  -G "Visual Studio 14 Win64" ^
   "C:\Program Files (x86)\IntelSWTools\openvino\deployment_tools\inference_engine\samples"

即使我更改为 visual studio 16 但给出了相同的错误，它也会引发以下错误：

(base) C:\Users\ra\build>
(base) C:\Users\ra\build> "C:\Program Files\CMake\bin\cmake.exe" ^
More?   -G "Visual Studio 16" ^
More?    "C:\Program Files (x86)\IntelSWTools\openvino\deployment_tools\inferenc
e_engine\samples"
CMake Error at CMakeLists.txt:7 (project):
  Generator

    Visual Studio 16 2019

  could not find any instance of Visual Studio.



-- Configuring incomplete, errors occurred!
See also "C:/Users/ra/build/CMakeFiles/CMakeOutput.log".

但是当我使用这个命令时：

 "C:\Program Files\CMake\bin\cmake.exe" ^
 -G "Visual Studio 20" ^
 "C:\Program Files (x86)\IntelSWTools\openvino\deployment_tools\inferene_engine\samples"

它抛出生成器错误为：

e_engine\samples" CMakeLists.txt:7（项目）处的 CMake 错误：发电机

Visual Studio 15 2017

找不到任何 Visual Studio 实例。

-- 配置不完整，出现错误！另请参阅“C:/Users/ra/build/CMakeFiles/CMakeOutput.log”。

我运行的是 Windows 7 64 位，都安装了 CMake 最新版本。帮帮我。

【问题讨论】：

错误信息很清楚，你的机器上是否有 Visual Studio installed 的实例？此外，在调用 CMake 时，您必须使用格式正确的生成器名称，例如 "Visual Studio 16 2019" 或 "Visual Studio 14 2015"。这些也列在错误消息中。
我已经安装了很多次Visual Studio，还尽可能写了所有生成器名称都给出错误;(
您安装了哪个版本的 Visual Studio？您是否尝试从 Visual Studio 开发人员命令提示符运行 cmake 命令？您可以从 Windows 开始菜单访问它。
刚刚我今天又下载了它，我正在解决的这个错误是那个 openvino 不支持的 avx，我做了所有我被困在这个error
是的 cmake 没有在 Visual Studio 命令提示符下运行

标签： cmake intel avx avx2 openvino

【解决方案1】：

您可以使用 bat 脚本自动构建演示：

"C:\Program Files (x86)\Intel\openvino_2021\inference_engine\demos\build_demos_msvc.bat"

如果您愿意，也可以手动构建它们。

"C:\Program Files (x86)\Intel\openvino_2021\bin\setupvars.bat"
md build
cd build
cmake -A x64 "C:\Program Files (x86)\Intel\openvino_2021\inference_engine\demos
cmake --build . --config Release

请确保您的系统符合system requirements 并且您使用的是受支持的操作系统。对于 Windows，仅支持 Windows 10。
