Hello everyone,
I have locally modified the <make> task to account for the -j
option... I still cannot build qt-jambi completely (it fails at the
native jar stage because it cannot find libsdtc++...), but at least
with this patch, it fails earlier :p
What do you think about generalizing it? For now, it only every does
the correct thing if GNU Make is used, I don't even know if other make
versions support this option...
And BTW, in this same <make> task, the make executable is confusedly
(imho) called the "compiler", what about replacing compiler with
makeExecutable all around?
