cmake crashes due to missing libidn

[illogic-al@…]

Cmake port is missing a libidn dependency which leads to it crashing. To reproduce, install macports 1.7.1, port sync, and give the foll. command sudo port install amarok-devel

Should also work if you just deactivate libidn and install a port which requires cmake to build. or just run cmake from the command line. Which will both take less time than the above command.

Crash output:

btw, this is weird because cmake shouldn't depend on anything.

[illogic-al@…]

OK. so I uninstalled then installed cmake and then it just worked. And libidn is still uninstalled. Didn't port sync or do any updates in between. Weird. File under #heisenbug and close.

Could be a case of opportunistic linking, when building cmake it sees libidn so links to it; perhaps cmake has some way of telling it to ignore libidn when installed?
