abseil
Build fails vcpkg (x64-linux)
Describe the bug
Its' not possible to use abseil in x64-linux. It seems some sort of ABI problem (on windows the compilation works). I have already reported this bug on vcpkg repository (https://github.com/microsoft/vcpkg/issues/21625), but they asked to report here because looks like a upstream bug.
Steps to reproduce the bug
A git repository with the code and compilation steps
What version of Abseil are you using? 20210324
What operating system and version are you using Linux (Ubuntu 20.04)
What compiler and version are you using?
- Compiler: g++ 11.1.0

What build system are you using?
- CMake (3.21.3)
Aditional information I'm using the cxx17 feature, and the logs say someting about cxx11, but I already made sure that the cxx17 feature is anabled by looking at the abseil files generated after the patch to use std::any, std::optinal, std::string_view and std::variant.
The issue is almost certainly that Abseil isn't being built with the same C++ language version as your program is. Additionally, the vcpkg version is not supported by us.
