[Insight-users] Building ITK with multiple cores

[Bill Lorensen]

It should work. CMake should handle it, although I have seen
intermittent problems with the intel compiler on linux.

For the time being you can do:

make -k -j3;make -k -j3;make -k -j3;make -k -j3;

You can file a bug report, but this is a pretty low priority item.
