[ITK Community] [Insight-users] [Insight-developers] Problem linking libraries ITK-Cmake

[Jon Haitz Legarreta]

Hi Alessio,
are you building *OtherLibrary* as a library itself (be it dynamic or
static)?

If you want to use it as a library you shoud build it first (i.e., you
should write its own CMakeLists.txt, configure and generate the project,
and build it), and then you should be able to link against and use it from
other projects.

HTH,
JON HAITZ
