Acceleration of 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 the GNU tool users were getting the full benefit of new dual and quad core processors by parallelizing the build with make -j, Visual C ++ users gathered Qt into one “thread”.

But the Qt developers did not forget about the Visual C ++ users and released the jom utility for them ( source , 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 the directory from the PATH and run instead of nmake.

Happy building!
