Building an Application

Normally, the only change needed to build your application with MPI FFTW wrappers replacing original FFTW3 library is to add
Intel® oneAPI Math Kernel Library
and the wrapper library at the link stage (see section "
Linking Your Application with
Intel® oneAPI
Math Kernel Library
" in the
Intel® oneAPI Math Kernel Library
Developer Guide
).
When you are recompiling your application, add subdirectory
include\fftw
to the search path for header files to avoid FFTW3 version conflicts.
