WS fails with DevStudio 17, MSVC 14.16.27023

[mbrunecky]

Describe the bug While using cmake on tesseract 5.1, WS fails to compile (multiple files) with MSVC reporting: C:\Users\mbrunecky.sw\storage\pkg\e2\99\efe6\src\sdir\src\string\include\primitives/string.h(42): error C2039: 'u8string': is not a member of 'std'

Expected behavior I do not know why WS is downloading, checking and compiling hundreds of packages/files,. However, per tesseract documentation invoking the following sequence should produce a DevStudio solution for tesseract development:

git clone https://github.com/tesseract-ocr/tesseract tesseract
cd tessersact
mkdir build
cd build
cmake ...

But instead, it fails with hundreds of errors.

To Reproduce Steps to reproduce the behavior:

cd tesseract\build
cmake ..

Information:

• sw.client.sw version 1.0.0 git revision 8d2a117e66deea583b45815150e78d76444b7137 assembled on 20.12.2021 11:02:00 UTC 20.12.2021 04:02:00 Mountain Standard Time

• Windows 10

• HP 440 workstation

Dev Studio 17, repeatedly updated and 'repaired' (making sure it is not damaged). As far as I can tell, the Standard Library (part of DevStudio 17) does not define/recognize std:u8string used in multiple WS files.
