[Build routine] Progress bar for visualisation?

[kevinmatthes]

How about adding a progress bar such as the one apt has to the build routine? This would be an enhancement for the users who build NFFT for the first time since they would know what is already done in comparison to the whole build step.

As a measure of progress, I would like to suggest the count of already executed instructions.

I do not think that this is an important feature because the full compilation usually takes less than 5 minutes and the duration of the different steps highly depends on the system (e.g. the checks in the configure script work much faster on linux than on msys2 in windows).
