Hi all,
I am installing [Caffe](https://github.com/BVLC/caffe/tree/windows) for windows 11. In one of the steps ( running `C:\Projects\caffe> scripts\build_win.cmd` according to the installation guide on Caffe github page), I get the following errors:
> `-
```auto
- Detecting C compiler ABI info - failed`
> -- Check for working C compiler: C:/Program Files (x86)/Microsoft Visual Studio 14.0/VC/bin/amd64/cl.exe - broken

```
Do you know what is the problem and it can be solved?

the following is the complete response in the cmd:

Did you run vcvars and setup your compiler environment?

before this, I got errors for vcvarsall.bat that couldn’t be found in the VC folder VS 14.0 directory.
Apparently, I have multiple versions installed and this file was in under another directory. what I did was I moved it from directories of previous versions to V14.0:
I also got errors regarding C and CXX compiler environments. I re-installed it and now it seems those errors are gone.
does this answer your question? I might miss some details here and there because I don’t have much experience working with these programs.

So, you should make sure that your compiler is installed correctly and working from the command line that you are running CMake from. To test this create a very simple c++ program in foo.cxx.
`int main(int, char**) { return 0;}`
You should then be able to compile it without error like this:
```auto
cl foo.cxx
Microsoft (R) C/C++ Optimizing Compiler Version 19.29.30136 for x64
Copyright (C) Microsoft Corporation. All rights reserved.
foo.cxx
Microsoft (R) Incremental Linker Version 14.29.30136.0
Copyright (C) Microsoft Corporation. All rights reserved.
/out:foo.exe
foo.obj
```
Once that works CMake should work.
