Increasing the compilation speed
You can speed up the compilation on a multicore computer. By default, when you build your project with Qt Creator, you only use one job (and, therefore, one core). But make supports the compilation with multiple jobs. You can use the make -j N option to allow N jobs at once. Do not forget to update your packaging scripts!
If you build your project from Qt Creator, you can set this option from Projects | Build Steps | Make. Click on Details, then, in the Make arguments field, put the value -j 8 to allow eight jobs during the compilation, as shown in the following screenshot:
