Changeset 2129 for trunk/m4/yat_gsl.m4

Timestamp:

Author:

Message:

New configure option 'with-gsl=DIR'. This option also accepts 'no' as
an argument or equivalently '--without-gsl' in which case no check for
GSL will be performed. The old --with-gsl-prefix and
--with-gsl-exec-prefix are deprecated.

fixes #544
