Boost does not set the BOOST_FOUND variable to indicate that the
package is found (as it would if it had used the usual routine
find_package_handle_standard_args), but rather Boost_FOUND. This
patch tests for that condition, and print some more helpful debug
messages if a prerequisite is missing.
If an optional package require further packages, those packages should
not be marked as REQUIRED because CMake will then terminate the
configuration if it is not found (although it is transitively optional).
Conversely, we should be able to specify REQUIRED prerequisites for
REQUIRED packages and have a failure cascade up to termination.
This changeset allows us to specify REQUIRED or not in the list of
prerequisites, and have OpmPackage sort of whether it should be honored
or not.
If it is already found, most packages sets a flag that makes it exit
immediately anyway. We usually cannot rerun find_package to get another
combinations of modules. Here we check the flag before we start looking
for the package to avoid the endless stream of messages.
Currently only the source tree is "searched", but the template could
be expanded to look in another/more locations (or be specified
explicitly on the command-line with a --with-opm-macros= option)
By default the configure script assumes that the source is located
relative to the script itself. By allowing this to be overridden, the
script can be shared by other projects, each passing their own location
as an extra parameter.
Currently this bootstrapper only finds the macros that are located
in the cmake/ tree in this project. Projects that don't carry their
own build system can specify search locations here.
By using a separate variable for this we can easily grep for where
the build system depends on its own location, and also change the
policy regarding this later.
Note that there is no opm-macros module; this is a "psuedo"-module
which links to an additional one (currently, the one we're in)
ALUGrid is needed to avoid unresolved symbols if dune-grid was
compiled with it. METIS is used by the parallel version of
ALUGrid. (Although it is not open source...)
This define is used in a opm/*.c* file, but only there, and should
therefore be in config.h, but not added to the list that only clients
must also provide.
The modules declare which configuration variables they need to have
present in config.h, not only their own but also defined in projects
using them.
However, a lot of these variables are not actually used in the headers!
This changeset removes all HAVE_XXX variables which is not present in
any opm/*.h* file in these projects, and thus there is no need for the
client to specify.
Note that only the variables used by the module *itself* should be
listed; the build system will setup the complete list from the
prerequisites.
This define is used by the unit tests; there is no reason why it should
be on the list that must be provided by other projects that use our
headers (the other projects don't use our tests).
The interface of the class PersistentContainer changed between DUNE
2.2 and DUNE 2.3 in an incompatible way, so we need to present
different versions of the class depending on the version of DUNE linked
with. This changeset adds the version variables for dune-grid to the
list of publicly necessary #defines that must go into using
dune-cornerpoint.
Notice that this will cause the definition of DUNE_GRID_VERSION_XXX
to be added to the flags list of dune-cornerpoint. This can be seen as
either a bug or a feature. If you try to link first dune-cornerpoint to
one version and then to another version of DUNE later, there is a very
good chance that you'll end up with problems anyway.
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.

Resurrect support for AGMG library
This is an interim milestone that may serve as point from which to
resurrect the AGMG suppert fully if the AGMG author ever decides to
re-release the software under an open licence.
our policy is that we only use boost if necessary, i.e., if the oldest
supported compiler does not support a given feature but boost
does. since we recently switched to GCC 4.4 or newer, std::shared_ptr
is available unconditionally.
