glibc2.39: minimum kernel version 3.2

Upgrade gcc: https://github.com/docker-library/gcc/blob/master/14/Dockerfile

Before:
OS: Ubuntu14.04
Kernel version: 4.4
Compiler: gcc4.8.2
glibc: 2.23 (libc.so)
glibc++: 2.23 +- (libc++.so)
c++ standard: < 11

After manual upgrade:
OS: Ubuntu14.04
Kernel version: 4.4
Compiler: gcc14.0.0
glibc: 2.39 (libc.so)
glibc++: 2.39 +- (libc++.so)
c++ standard: < 29 +- (accept c++23)

We must remove all find_package and add dependencies as submodule or CPM and compile

• curl
• protobuf
• grpc
• ...

We can compile all with c++23 standard
Link all static (include glibc)
Profit!

We can ship userver work with minimum kernel version 4.4

userver-all-linux-amd64.deb
userver-all-linux-arm64.deb
userver-all-macos-amd64.deb
userver-all-macos-arm64.deb

Pros:
+ control version of all dependencies (It won't happen that updating some dependency will break build, we can use latest version of all dependency)
+ we can stop thinking about supporting old versions of dependencies
+++ user-friendly (anyone can download our single .deb and immediately write a microservice without worrying about missing any dependencies)
+ we will be able to get the same stacktraces absolutely everywhere
+ we can compile with any с++ standard

Cons:
- if CVE is found in any dependency, we must manually update version with fixes this dependency, recompile and re-upload .deb
- the first time it will take time
