<DIV>First of all, thank you bery much for replying. </DIV>
<DIV> </DIV>
<DIV>- my 3 files <STRONG>fftw3.h, fftw3.lib and fftw3.dll</STRONG> are in the same directory <STRONG>C:\FFTW3_LIBRARIES</STRONG>.</DIV>
<DIV> </DIV>
<DIV>- once I got them, I modify my <STRONG>FindFFTW3.cmake</STRONG> as reported. Here is my FindFFTW3.cmake:</DIV>

<P> </P>
<P>MARK_AS_ADVANCED(FFTW_INCLUDE_PATH FFTW_LIB_PATH)</P>
<P>ENDIF (USE_FFTW)</P>
<P> </P>
<P>-then, I use <STRONG>CMake</STRONG> to <STRONG>enable FFTW in ITK</STRONG>: with <STRONG>USE_FFTW = ON</STRONG></P>
<P> </P>
<P>- after that, I use <STRONG>CMake to config my own project</STRONG>. Here is my CMakeLists.txt for this project: </P>

<P>With CMake, I got the following error, <STRONG>CMake Error: FFTW_DIR is set to C:\FFTW3 which is not a directory containing FFTWConfig.cmake. </STRONG></P>
<P> </P>
<P>And now, I am still locked there. Of course, I look for this FFTWConfig.cmake but couldn't find it.</P>
<P> </P>
<P>Do you see something wrong? </P>
