This may be a BUILD ticket, but we'll investigate on the WT side first.

Commit WT-10456 introduced some changes to workgen that make use of the filesystem library added in C+17. This should be fine as WT supports C+17 - and has CMake checks enforcing a C++17 compliant compiler - but we're seeing the following errors in evergreen tests and when running locally:

ImportError: /data/mci/47e37614325f95f8a45c0afef1f0f3ad/wiredtiger/cmake_build/bench/workgen/_workgen.so: undefined symbol: _ZTINSt10filesystem7__cxx1116filesystem_errorE

[2023/01/09 11:15:54.592]  #include <filesystem> 

This can be fixed on local machines by forcing the v3 compiler. Courtesy of Will:

You can work around this by forcing /usr/bin/c++ to point to the mongo toolchain v3 c++ compiler. (v4 doesn't work unfortunately, since the system libc++ is too old for gcc 11.)
