[Insight-users] compilation problem

[Luis Ibanez]

Hi Fleming,

You are probably adding the libraries in the wrong order
in the CMake command TARGET_LINK_LIBRARIES.

Could you please post to the list that section of your
CMakeLists.txt file ?

Please note that in Unix the order of the libraries is
important. High level libraries must go first.


   Thanks


      Luis

This was configured for cmake so that I can compile the sources for the object files and link them to the executable. As soon as I add any calls to ITK, however, I can't compile.
