This file can be included both in the project itself, and also in the
find module for the library, so that the list of dependencies can be
maintained in only one place.
This let you specify a bunch of directory names on the command line
to *all* packages, without getting annoying warnings that they are
defined but not used.
When using LTO, the linker calls back to the compiler to figure out
where a certain symbol is defined. However, in many versions there
is apparently a bug that is triggered if a template in inlined in
both a used library and in the main program, but with different
versions of the compiler. The Boost exception class is particular
prone for this.
Thus, we disable the -lto from the development builds by default;
if anyone wants to test of the behaviour of their own compiler, they
must now explicitly turn on this flag.
If a client generated with duneproject/built with dunecontrol has a
dependency to opm-autodiff, the macros defined in this file is expected
to exist and will be called to search for the opm-autodiff library.
All that is done here is to use the pkg-config helper module and
import the configuration that was written by the CMake system (which
even may have been called earlier in the same dunecontrol "session")
Pkg-config files are written as part of the CMake configuration, and
these can be imported into AutoTools-driven projects to get the correct
compiler and linker options that has been probed.
Fall back to Eigen's BiCGSTAB solver if UMFPACK is not available. The
BiCGSTAB is built into Eigen and consequently always available when
Eigen is found.
Not all systems provide UMFPACK so even if Eigen provides the required
bindings, we should not assume that the underlying library and/or
headers are available. Currently, only examples/sim_simple.cpp uses
UMFPACK unconditionally, so the simplest solution is to exclude that
example unless UMFPACK is available.
Not all implementations support the TR1, and if they do, the type
might not be in a namespace called std::tr1 . Favour the
implementation from Boost for reasons of portability.
This is inspired (and necessitated) by commit OPM/opm-core@68eb3fb
which, incidentally, cleaned up some header pollution on which we
inadvertently depended.
By setting EIGEN3_ROOT, we can point directly to the path of the
library checkout we want to use. No other searching will then take
place.
Notice that if you have found an Eigen3 installation in a previous
configure, it will not find a new version even if you introduce the
EIGEN3_ROOT variable!
- Using x/x.abs() instead of a proper sign function led to problems
when x = 0. Solved by using new sign() utility.
- Pass pressure instead of rs as parameter to fluidRsMax().
