[Insight-developers] FFTW not working

Tue Apr 19 10:39:30 EDT 2011

I'm doing a build right now to see if I can duplicate the problem.

There seems to be a problem with respect to where the FFTW header files
are being searched for; the place the files are being installed --
${CMAKE_BINARY_DIR}/fftw/include -- isn't on the include path.

I'm testing a fix for this, but since it involves changing compiler flags,
it's triggered a complete rebuild of ITK.

If you want to try it yourself, this is what is involved.

diff --git a/CMake/itkExternal_FFTW.cmake b/CMake/itkExternal_FFTW.cmake
