If you simply did ./configure, make, make install, then the default location for 
installing the libraries is in /usr/local/lib and /usr/local/include, not the 
source tree.  If you have lib/ and include/ subdirectories within the source in 
~/Desktop/fftw3.3.4, then you did install it there, but that requires explicitly 
setting that location with ./configure --prefix.

That indicates the libraries and headers are not, in fact, installed within
