Yes but I'm using MinGW make (on Windows machine), the interpreter is
GNU Make 3.82

When I launched the make project I also checked the child process
creation, the parent process is:
c.\...\cs-make.exe -j 2 all
but the child process is:
c:/.../cs-make -f CMakeFiles\Makefile2 all
Than, after a clean, I manually launched:
c:\..\cs-make.exe -j 2 -f CMakeFiles\Makefile2 all
In this way I reduced the build time from 25 min to 14 min.
Could MinGW-make have a different behavior from gmake?

I generated a MakeFile Project (MinGW) and I'd like to speed up the
build process using -j N option. So I launched:
"make -j 2 all".
Unfortunately I noticed that the Makefile, generated by CMake self,
contains this row: $(MAKE) -f CMakeFiles\Makefile2 all , so Makefile2
won't be executed in parallel mode.
How can I pass this option to all build steps?

gmake will do the right thing. when you run a toplevel make with -j2
it will set an env var that is passed down to the $(MAKE) and it
should work. I use it all the time.
