[Ctk-developers] install CTK from ExternalProject_Add

[Sascha Zelzer]

Hi Miklos,

ExternalProject_Add() does not know if the external project has a 
super-build structure itself or not. So calling "make install" on the 
CTK superbuild level *should* do the right job, which it currently 
doesn't (as you have described). In case of external dependencies which 
the CTK superbuild resolved, you would typically want to install them as 
well.

I am currently working on exactly this feature (we would like to do a 
"make install" for CTK in MITK as well), see

Best,
Sascha
