[Rtk-users] ITK cmake settings

[Simon Rit]

Hi Cyril,
Very good questions.

ITK_USE_REVIEW is ITK 3.20 related, I don't think it is required in ITK 4.

It is very much advised to use FFTW because it is faster and more
flexible in terms of projection dimensions. Both single and double
precision can be turned on. It works for me, can you send us a report
on the conflict you get? Do you use the system fftw or you let ITK4
download it?

In order to track bugs in your code, yes, you need to compile ITK with
debug or RelWithDebInfo because the crash might be in the itk part and
even if not, the compilation might be difficult (if possible) with itk
in release and rtk in debug.

There is no recommendation with shared libraries except that we have
encountered difficulties in the past with shared libraries and cuda.
You'll probably have to add a -fPIC options to make it work. I am used
to use static libraries by default but I don't have a real good
argument for this.

I would also recommend turning off BUILD_EXAMPLES and BUILD_TESTING
for rapidity and ITK_BUILD_ALL_MODULES in itk4 to be sure that you
have everything required.
Don't hesitate to report any other option that we would have overlooked.
