Conversion happened in the constant vectorXi construction.

Allow C++17 language features.

This forcefully brings updates to Eigen-3.3, gtest as a submodule, and changed cmake scripts.

In multi-threaded environments multiple ctests running
parallel fight for the same cpu threads otherwise.

Failing on mac now with error 9.2e-7 since c++17/Eigen-3.3 change.

MacOS repeatedly could not finish in 3h.

The original initialization of the std::array's was by copy anyway
and somehow caused in seg faults on mac after adding c++17 standard.

Contains up-to-date FindPETSc and FindNetCDF.

The original gtest folder is removed.

Reason is the removed namespace std::tr1 no longer available in the VS2017.
Fixed in PR https://github.com/google/googletest/pull/1218
and the related issue is https://github.com/google/googletest/issues/1138

The latter takes a random generator while the former uses
std::rand implicitly.
The std::random_shuffle was marked deprecated and is removed
from the c++17.

Related to c++17 removed binder* functions.
Fixed in http://eigen.tuxfamily.org/bz/show_bug.cgi?id=1276
http://eigen.tuxfamily.org/index.php?title=ChangeLog#Eigen_3.2.10

Other binder* functions were removed only in the 3.3 branch.

The `bool uncaught_exception()' is deprecated since c++17
and is replaced by `int uncaught_exceptions()'.

BGRa benchmarks

[Jenkins] Use new syntax for warnings plugin.

https://github.com/jenkinsci/warnings-ng-plugin/blob/master/doc/Documentation.md

When the SolidEhlers ctor is not used it was not generated in the library.

Convert double array to int array

Consistent ticks

Only in ERR/WARN/INFO/DBUG/OGS_FATAL and similar, not in
formatted output like xml files.

SmallDeformation nonlocal

Fixed the documentation for an used parameter

Same function is used in Ehlers and in the LinearElasticIsotropic.
