How to compile part of ITK integrated into another library?

[al-sabr]

@dzenanz

Maybe one of the libraries involved is single-configuration only? Try making a clean build, and put only Release into CMAKE_CONFIGURATION_TYPES (instead of the default Debug;Release;MinSizeRel;RelWithDebInfo).

Which one you think it is? KWSys???

[dzenanz (Dženan Zukić)]

KWSys should respect that, as it does that while being part of ITK. Maybe Blueberry or mbilog?

[al-sabr]

I removed the KWSys from ITK and imported the original from Kitware’s repo : https://gitlab.kitware.com/utils/kwsys

It has nothing to do anymore!

Can you check why CTKmitk is not compiling with this error:

Modularized itk as CTKitk, mitk as CTKmitk.

Why is it that itk & mbilog are linking but not mitk (libraries look at structure in Libs)

[al-sabr]

@al-sabr

Damn it was so much waste of time when I could use something much more simpler!

I found out from CTK developers easier way to integrate external dependencies without going through rough modifications.

[al-sabr]

The solution continues on github https://github.com/commontk/CTK/issues/949

[dzenanz (Dženan Zukić)]

I think I also mentioned using external project approach to you instead of modifying the libraries. JC has more experience in build systems than me, and he is also one of the maintainers of CTK. And your fork of CTK has more to do with CTK than ITK

[al-sabr]

@dzenanz I’m sorry if I didn’t get it when you proposed it and that’s because I am a noob in CMake and large project.

But I am learning a lot here due to exchanging ideas and trying to understand few bits and pieces.

I appreciate your support.
