Do initial research on parser generators. Look at https://www.gnu.org/software/bison/

Parsing with bison:

it's simply addable with cmake
we have to create parse.y file in bison syntax
we can use already existing parse.y files (https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=gcc/c-parse.in;h=66d27ac0322f335aed8a3302522bcf19ffc9d1bf;hb=359e576cf4a70392fda974114498ba451310ab05)

Using existing parse.y could be a good idea. With the once you posted we do not need to use separate lexer as bison will do the job of the both of them.

Alternatively we can use both flex and bison. Those two should do the job: https://www.quut.com/c/ANSI-C-grammar-y-2011.html https://www.quut.com/c/ANSI-C-grammar-l-2011.html
