So I setup fftw folow the fftw website .
lib /machine:x64 /def:libfftw3-3.def
lib /machine:x64 /def:libfftw3f-3.def
lib /machine:x64 /def:libfftw3l-3.def
then set the include library,lib library ,and add
linker input libfftw3-3.liblibfftw3f-3.liblibfftw3l-3.lib
copy the libfftw3f-3.dll libfftw3-3.dll libfftw3l-3.dll to system path
it's trouble.
Is there a easy way?
