Local installation of antlr4 when pointed to cpp standard v17 (from v11) does not compile anymore

[Tephilla]

Background:
Been using antlr 4.9.2.2 on windows wsl setup.
My code base previously used cpp 11 and since antlr4 has moved on, I pointed it to cpp17. Now, I cannot make the project and throws an error in the Lexer file.

Issue:
On running make all, I still get the following error. generated/ is the directory that holds all the generated antlr-specific files

g++ -c -w -I /usr/include/antlr4-runtime/ -I generated -std=c++17 generated/*.cpp *.cpp
In file included from generated/DOCLexer.cpp:5:
generated/DOCLexer.h:34:43: error: ‘virtual const std::vector<std::__cxx11::basic_string >& DOCLexer::getTokenNames() const’ marked ‘override’, but does not override

I checked that the antlr4 libraries are present. For instance, my make file points to the following locations which are correct paths.
/usr/include/antlr4-runtime/
/usr/lib/x86_64-linux-gnu/libantlr4-runtime.a

What am I doing wrong? Can someone point me in the right direction to resolve this dependency issue?
