Hi,
A number of package using cmake and qmake currently do something like this:
LANGS="en de fr"
for x in ${LANGS}; do
IUSE="${IUSE} linguas_${x}"
done
This is ugly, so for some time the loop has been included in qt4-r2, and
I'd also like to add it to cmake-utils.
As far as I can see, this change will have no visible effect on ebuilds
that already manually include the loop, and will cause only one package
to get linguas_* flags that it doesn't already have (which I'll fix).
Thoughts?
