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

[Martin Styner]

Hi everybody

I found an oddity in the behavior of cmake with itk. When I am using a 
locally built VTK instead of an installed VTK, the CXXFLAGS and CFLAGS 
will be taken from the VTK part instead of from ITK. 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).

Is the above behavior (VTK definitions superseeding the itk definitions 
for the compilation flags) intended to be like this, or is it an error ?
