Unable to build CLI

[bradleyhodges]

Hi,

I'm unable to build the CLI as described in the README. I have Python 3.10.2, CMake 3.22.2, and Visual C++ Redistributable 2015-2022 x64 installed. When attempting to build, I run into the following issue.

Despite troubleshooting, I end up in the same place every time:

Traceback (most recent call last):
  File "build.py", line 942, in <module>
    BUILDER = Builder()
  File "build.py", line 931, in __init__
    self.build_dlib()
  File "build.py", line 421, in build_dlib
    self.build_cmake_lib(dlib_extract_dir, cmake_extra_defs, ['install'], True)
  File "build.py", line 521, in build_cmake_lib
    self.run_cmd(cmake_cmd)
  File "build.py", line 219, in run_cmd
    cwd=cwd, input=input)
  File "build.py", line 143, in run_cmd
    cmd_all = [self._vcvarsbat, vs_arch[self._arch_name]] + \
AttributeError: 'ShellRunner' object has no attribute '_vcvarsbat'

I'm closing this issue as I have resolved the issue. The build script looks for the vcvarsall.bat script in hardcoded locations. I installed Microsoft Visual Studio 2017 (I had 2019 Enterprise installed), and build succeeded.
