Building issues: small propositions

[kerim371]

Hi,

I was trying to build OpenSeaSeis with SU support on Ubuntu 20.04.
At first I got an error that EXEC_TYPE_MULTITRACE was'nt declared at this scope.
I think it should be EXEC_TYPE_INPUT (or EXEC_TYPE_NORMAL please correct me so I could rebuild it correctly).

Also in the documentation How to install FFTW I think it should be noted that --enable-shared is required as well.

With these fixes I could build it correctly, thank you :)

Also I encountered errors with this file:

OpenSeaSeis/src/cs/modules/fft/mod_fft_0.5.cc:443:32: error: ‘class cseis_geolib::csFFTTools’ has no member named ‘fft_forward’
  443 |       success = vars->fftTool->fft_forward( samples );

Link to the source code

I think there are other issues with this file as well.
I downloaded latest FFTW 3.3.10
