High build times in the Shooter Game example

I based my project of the shooter game example and I have some really troubling compile times.

A minor change in ShooterCharacter.h will always result in a compile time of at least 70sec. Changing only the .cpp will results in a faster build time as expected. (30-60sec).

I have and i5 with 4 threads and 8 gigs of ram. Everything is on an SSD besides visual studio. Are those build times normal?
