Im having trouble linking fftw3 properly with the CMakeLists.txt.
I've tied updating the CMakeLists.txt with proper file names but ultimately reverted and put symbolic links directly in the paths that CMakeLists.txt claimed it would be searching. however cmake still cant find the items -can anybody tell me wat Im doing wrong?
btw - (fftw3 was compiled via macports as fink finished with errors.)
Thanks in advance for any help you can offer.

Here is my process:
I unpack the tar.gz in the user dir:
Code:
tar -xzvf arss-0.2.3-src.tar.gz
the CMakeLists.text indicats that cmake will be looking for fftw3.h in /usr/local/include
Now at this stage I tried updating the CMakeLists.text to reflect the actual paths to fftw3.h as installed by macports in opt/local/include, but in the end opted to made symbolic links for files and paths from where I found them in the various macports paths /opt/local/ to where CMakeLists.txt indicated.
From CmakeLists.txt
Code:
FIND_PATH (FFTW3_INCLUDE_DIR fftw3.h PATHS /usr/local/include /usr/include /sw/include)
#which I found in opt/local/include/fftw3.h
FIND_LIBRARY (FFTW3_LIBRARY fftw3 fftw PATHS /usr/local/lib /usr/lib /lib /sw/lib)
I couldn't find FFTW3_LIBRARY fftw3 fftw at any of those paths but I did find
libfftw3.3.dylib in opt/local/lib/
So I created symbolic links bridging these.
Code:
sudo mkdir /usr/local/include
ln -s opt/local/include/fftw3.h /usr/local/include/ffw3.h
sudo li -s opt/local/lib/libfftw3.3.dylib usr/local/lib/FFTW3_LIBRARY
I've found under the INSTALL note that the command to compile with cmake:
Code:
cd /arss-0.2.3-src/src/
cmake . && make && make install
cmake still cant find fftw3.h and quits with errors
Here is the terminal output:
Code:
ibook-1:~/arss-0.2.3-src/src barefoot$ cmake . && make && make install
