<br>
Thanks, Dženan, for the hint. But, does anyone have specific information on exactly which options to set in each of: the ITK cmake options; and the project cmake options, or the plain g++ for building an external program to link to the library, for this to
 work ? There appear to be a few that might be related to this. Because, so far, simply changing the build options of the ITK installation didn’t work. See below for even more details .<u></u><u></u></span></p>

<p class="MsoNormal">Hi,<br>
This example, ITKApps/ITKFilterLib, appears to be an example of what I want to do , bundle or encapsulate  a specific ITK-based filter into a library so that another program may just call it without having to have the ITK source installation available.<br>
However, a basic test for me is not working.<br>
<br>
I just tried to compile the test example from command line after building the library with Cmake as usual. I get hundreds of 'undefined reference', as if I have to link with all the ITK libs anyways.<br>
Am I missing something?<br>
Thanks<br>
