[ITK] How do I generate the ITKMorpholigical library?

Wed Jan 28 14:37:33 EST 2015

Hello,

The header file reside in the source directory of ITK[1], and does not need to be moved to the build directory where object files and libraries are created during the build process.

When the INSTALL target is run on the ITK project, all the libraries, cmake interface files along with the header, and template header files are copied to the specified installation directory.

When you use ITK with CMake, and find and include the ITK cmake[2] files, it will automatically add the correct include paths to the compiler for all the ITK files available for either of the above cases.

Does that explanation help?
