[Insight-users] compiling flags using build VTK instead of installed VTK

[Bill Lorensen]

Martin,
This is the expected and required behavior. The builds must have compatible compile flags. Of course, in the case of optimization or debug level there would be not harm in having different flags. But, in many cases, different flags will cause problems.

E.g. If I am compiling VTK with '-O2', then I can't get itk to compile without the '-O2' flag! Well, there is a work-around, I just reran ccmake in the VTK directory, changed the compilation flags and generated the makefiles (of course without rerunning the compilation itself). Then I reran ccmake in the itk directory and regenerated the makefiles and everything was like I wanted it (no '-O2' for itk).
