The 8.4.1 cmake throws an error because of the "-gdwarf-2" flag on the
Intel compiler. Is that flag needed? If no, how can I disable it?
This is what I found in the CmakeError:

Source file was:
struct foo
{
auto func();
};
int main()
{
foo bar;
}
Here is my own experimenting:
[staff:compiler:109] cat auto.cxx
struct foo
{
auto func();
};
int main()
{
foo bar;
}
[staff:compiler:110] mpicxx -std=c++11 -c auto.cxx
auto.cxx(3): error: "auto" function requires a trailing return type
auto func();
