[CMake] Why does build_command() return a command that ignores errors?

[David Cole]

Here's a guess:

For dashboard submissions, some prefer to see *as many errors as
possible* at once in one go, so as to have the least turnaround time in
fixing errors on a remote system without having direct access to that
system.

To accommodate such a preference, the default flags have included -i
for years now...

So changing it now would be a behavioral change / backwards 
compatibility issue.

However, looks like this becomes a moot question as of 3.0:
