Hi, to whom it may concern:
Eigen seems to be always problematic under Windows.
I'm trying to use the released version 3.0.5 . However, when I tried to configure Eigen using CMake 2.8.7 GUI under Window7 (32bit),
it's weird there is no "FFTW_INCLUDES" for me to specify,.
Therefore, I add a new entry "FFTW_INCLUDES" manually, I still get the following error message
Could NOT find FFTW (missing: FFTW_INCLUDES)
Then, I did a full search under the folder "eigen"
C:\packages\eigen>grep -r "FFTW_INCLUDES" ./*
./build/CMakeCache.txt:FFTW_INCLUDES:PATH=FFTW_INCLUDES-NOTFOUND
./build/CMakeCache..txt://ADVANCED property for variable: FFTW_INCLUDES
./build/CMakeCache.txt:FFTW_INCLUDES-ADVANCED:INTERNAL=1
../cmake/FindFFTW.cmake:if (FFTW_INCLUDES AND FFTW_LIBRARIES)
./cmake/FindFFTW.cmake:endif (FFTW_INCLUDES AND FFTW_LIBRARIES)
./cmake/FindFFTW.cmake:find_path(FFTW_INCLUDES
./cmake/FindFFTW.cmake: FFTW_INCLUDES FFTW_LIBR
ARIES)
./cmake/FindFFTW.cmake:mark_as_advanced(FFTW_INCLUDES FFTW_LIBRARIES)
This doesn't make sense to me. Why is it so?
How can I enable FFTW in eigen 3.0.5 under Windows then?
Does that mean eigen will never support FFTW ever since?
When will eigen not be a pain for me ?
Every time when dealing with eigen under Windows, it's almost a nightmare....
Hope somebody may give me a hand.
Thank you very much.
Best Regards
