Warnings can be controlled with "-Wname" and "-Wno-name" and "-Wall". When the same warning exists in gcc cakes uses the same name if possible.
Inside source code you can control warning like this
enum E1 { A };
enum E2 { B };
int main() {
#pragma CAKE diagnostic push
#pragma CAKE diagnostic ignore "-Wenum-compare"
if (A == B){}
#pragma CAKE diagnostic pop
if (A == B) {}
}
