Print build time
-
Is there any method to print a build time? I see that Qt Creator or qmake prints a message when make starts and stops. I want to print at the end of the build difference between them.
Example of Compile Output:
@

Qt Creator adds those time stamps.
A good way to get the desired time difference on linux/mac is to just add "time" in front of the call: It will measure different time values (cpu time, wallclock time) and print it once the application is done.
