It's an issue. In fact, long C++ compile times were supposedly one of the motivating factors of the Go language: "That 2007 [Google build] took 45 minutes using a precursor distributed build system; today's version of the same program takes 27 minutes, but of course the program and its dependencies have grown in the interim ... The origin myth for Go states that it was during one of those 45 minute builds that Go was conceived." [1] https://talks.golang.org/2012/splash.article https://talks.golang.org/2012/splash.article
