If we are using the Apple toolchain on MacOS X, we must use the
newer runtime and not the old GCC 4.2 fork, in order to get the
C++11 library features (such as std::shared_ptr).
AGMG is now under a closed-source license, meaning that results
obtained with this solver is not freely reproducible by others.
Its use is therefore discouraged.
As of version 2.3, the DUNE AMG parts are competitive, so there
is a free and open alternative.
When passing libraries to gcc/ld, the search path and library name must
be specified separately. This is already done when writing a libtool .la
and should be done in the pkg-config .pc file too.
Most of the file is not changed from some sensible default anyway, so we
can store this in the template directory and have a much more manageable
local file which just contains the relevant changes.
Templates can now be reused across projects. The output files are still
put in the root of the output tree because that is where the client
programs will look for them.
