So I'm trying to build the Affine Registration Filter which is an example offered by ITK.
The file builds, but I get a linker error which is saying that the gradient step optimizer is referencing an undefined base template. I checked in the corresponding ITK directory and the base template file is there. Also, when using the original gradient step optimizer (not v4) the file will link. There's either an error in the library (probably unlikely) or something on my system is throwing off linking.
Currently using cmake 3.11, Slicer 4 and ITK 4.13. I created a new Slicer extension through the wizard and added a cli module to it as a test bed if anyone wants to try and reproduce the error exactly.
Linking CXX shared library ../lib/Slicer-4.8/cli/modules/libImageRegistration9Lib.dylib
