I don't have a strong opinion on this, but the problem is the original line
`set(CLANG_DEFAULT_CXX_STDLIB "")` doesn't have actual effect (it seems to me).
I'm not sure what you mean by "temporarily reset the value". Last time I tested
it, `-DCLANG_DEFAULT_CXX_STDLIB=blah` doesn't reset the value to an empty
string (as expected?)
Anyway, I'm fine with either warning or erroring :)
