Comment(by jmalik):

 work in progress...

 The following snippet generates the def and lib file.
 I did not test yet the resulting .lib

 call "C:\OSGeo4W64\bin\o4w_env.bat"
 set pf=%ProgramFiles(x86)%
 if "%pf%"=="" set pf=%ProgramFiles%
 call "%pf%\Microsoft Visual Studio 10.0\VC\vcvarsall.bat" amd64

 set FFTW_DLL=%OSGEO4W_ROOT%\bin\libfftw3-3.dll
 set FFTW_IMPORTLIB=%~dp0\fftw3.lib
 set FFTW_DEF=%~dp0\fftw3.def

 for /F "delims=" %%i in ("%FFTW_DLL%") do set FFTW_BASENAME=%%~nxi

 for /f "usebackq tokens=4,* delims=_ " %%i in (`dumpbin /exports
 "%FFTW_DLL%"`) do (
   if %%i==fftw echo %%i_%%j >> %FFTW_DEF%
   if %%i==dfftw echo %%i_%%j >> %FFTW_DEF%
   if %%i==DFFTW echo %%i_%%j >> %FFTW_DEF%

 lib /machine:x64 /def:%FFTW_DEF% /out:%FFTW_IMPORTLIB%
