Yes.

Re-run cmake configuration in the build directory, double check the
CMake configuration variables, FFTWD_LIB, FFTWD_THREADS_LIB,
FFTWF_LIB, FFTWF_THREADS_LIB, FFTW_INCLUDE_PATH to ensure they are
correct and consistent, rebuild, and re-install.  The install step
will install the ITKConfig.cmake to /usr/local/lib/cmake/ITK-4.4/.

Hope this helps,
Matt
