Installation instructions
SETSM is dependent on the TIFF Library, which you must download and install separately. Download LibTIFF from http://libtiff.maptools.org/ and install it according to the instructions in the README file. In short, ./configure --prefix=/directory-to-install-in make make install
Once LibTIFF is installed you must edit the SETSM Makefile to set the correct path to the library. SETSM can then be built simply by typing make.
