This is a very bad idea.  This way you hardcode the build script towards your 
installation.

Do it this way:
  1. set the environment variable FC to the compiler you want to use
  2. set the environment variable FFLAGS to the flags you want to use
  3. run cmake

In your case this means
 1. $ export FC=/usr/bin/g77
 2. $ export FFLAGS=" -no-backslash"
 3. $ mkdir /path/to/builddir && cd /path/to/builddir && cmake /path/to/srcdir
