Speeding up Qt build with Visual C ++ compiler

Qt under Visual C ++ is built using nmake. nmake is an old tool that has not been developed for a long time. While GNU toolkit users were getting the most out of the new dual-core and quad-core processors by parallelizing the build using make -j, Visual C ++ users assembled Qt into a single “thread”.

But the Qt developers did not forget about Visual C ++ users and released the jom utility for them ( sources , binary ). jom determines the number of cores in the system and parallelizes the assembly.

Using the utility is extremely simple - you need to put it in a directory from PATH and run instead of nmake.

Happy building!
