[Insight-users] Re: ITK and C++ Builder (Segmentation and GUI), how glue it together?

Hello Emiliano and Michal,

Great hints from you, however my results weren't so successful since I 
guess I am some steps before of where you guys are. Could you please 
check the following steps and suggest me what is missing and how to go on,

1. Download and Compile ITK libraries with cmake (setting 
CMAKE_BUILD_TYPE = MinSizeRel). I got the makefiles, yes!

2. Then run make.exe to finally generate ITK libraries (itkcommon.lib, 
itkIO.lib and son on with itk*.lib). Done!

um, ?? :o| …then what? Can ITK libraries be stored and linked as static 
libraries and then use their classes from my project units?? If so, 
where are my header files (itk*.h)?? how can I link my libraries .lib to 
my bcb project??

I will really appreciate if could clarify this to me. Thanks for your 
kind help in advance.
