make the build of flow fully parallelizable so far, the actual specializations of the simulator were compiled into the `libopmsimulators` library and the build of the glue code (`flow.cpp`) thus needed to be deferred until the library was fully built. Since the compilation of the glue code requires a full property hierarchy for handling command line parameters, this arrangement significantly increases the build time for systems with a sufficient number of parallel build processes. ("sufficient" here means 8 or more threads, i.e., a quadcore system with hyperthreading is sufficient provided that it has enough main memory.) the new approach is not to include these objects in `libopmsimulators`, but to directly deal with them in the `flow` binary. this allows all of them and the glue code to be compiled in parallel. compilation time on my machine before this change: ``` > touch ../opm/autodiff/BlackoilModelEbos.hpp; time make -j32 flow 2> /dev/null Scanning dependencies of target opmsimulators [ 2%] Building CXX object CMakeFiles/opmsimulators.dir/opm/simulators/flow_ebos_gasoil.cpp.o [ 2%] Building CXX object CMakeFiles/opmsimulators.dir/opm/simulators/flow_ebos_oilwater.cpp.o [ 2%] Building CXX object CMakeFiles/opmsimulators.dir/opm/simulators/flow_ebos_blackoil.cpp.o [ 2%] Building CXX object CMakeFiles/opmsimulators.dir/opm/simulators/flow_ebos_solvent.cpp.o [ 4%] Building CXX object CMakeFiles/opmsimulators.dir/opm/simulators/flow_ebos_polymer.cpp.o [ 6%] Building CXX object CMakeFiles/opmsimulators.dir/opm/simulators/flow_ebos_energy.cpp.o [ 6%] Building CXX object CMakeFiles/opmsimulators.dir/opm/simulators/flow_ebos_oilwater_polymer.cpp.o [ 6%] Linking CXX static library lib/libopmsimulators.a [ 97%] Built target opmsimulators Scanning dependencies of target flow [100%] Building CXX object CMakeFiles/flow.dir/examples/flow.cpp.o [100%] Linking CXX executable bin/flow [100%] Built target flow real 1m45.692s user 8m47.195s sys 0m11.533s ``` after: ``` > touch ../opm/autodiff/BlackoilModelEbos.hpp; time make -j32 flow 2> /dev/null [ 91%] Built target opmsimulators Scanning dependencies of target flow [ 93%] Building CXX object CMakeFiles/flow.dir/flow/flow.cpp.o [ 95%] Building CXX object CMakeFiles/flow.dir/flow/flow_ebos_gasoil.cpp.o [ 97%] Building CXX object CMakeFiles/flow.dir/flow/flow_ebos_oilwater_polymer.cpp.o [100%] Building CXX object CMakeFiles/flow.dir/flow/flow_ebos_polymer.cpp.o [100%] Building CXX object CMakeFiles/flow.dir/flow/flow_ebos_oilwater.cpp.o [100%] Building CXX object CMakeFiles/flow.dir/flow/flow_ebos_solvent.cpp.o [100%] Building CXX object CMakeFiles/flow.dir/flow/flow_ebos_blackoil.cpp.o [100%] Building CXX object CMakeFiles/flow.dir/flow/flow_ebos_energy.cpp.o [100%] Linking CXX executable bin/flow [100%] Built target flow real 1m21.597s user 8m49.476s sys 0m10.973s ``` (this corresponds to a ~20% reduction of the time spend on waiting for the compiler.)

Make mixing incompatible host compiler/device compiler versions fail. We experienced weired linker errors when using host compiler version for compilation that were not supported by the nvcc used to compile the cuda code: ``` [ 15%] Linking CXX executable bin/test_timer /usr/bin/ld: /home/mblatt/src/dune/opm-2.6/opm-common/opm-seq/lib/libopmcommon.a(Parser.cpp.o): in function `Opm::(anonymous namespace)::file& std::vector<Opm::(anonymous namespace)::file, std::allocator<Opm::(anonymous namespace)::file> >::emplace_back<std::filesystem::__cxx11::path&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&>(std::filesystem::__cxx11::path&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&)': Parser.cpp:(.text+0x1096): undefined reference to `std::filesystem::__cxx11::path::_M_split_cmpts()' /usr/bin/ld: Parser.cpp:(.text+0x10ad): undefined reference to `std::filesystem::__cxx11::path::_M_split_cmpts()' /usr/bin/ld: /home/mblatt/src/dune/opm-2.6/opm-common/opm-seq/lib/libopmcommon.a(Parser.cpp.o): in function `Opm::(anonymous namespace)::ParserState::loadFile(std::filesystem::__cxx11::path const&)': Parser.cpp:(.text+0x23a1): undefined reference to `std::filesystem::canonical(std::filesystem::__cxx11::path const&)' /usr/bin/ld: Parser.cpp:(.text+0x24e0): undefined reference to `std::filesystem::__cxx11::path::_M_split_cmpts()' ``` The reason turned out to be that the library path was build up by paths of the old (g++-7) compiler used by nvcc and the actual (newer) compiler g++-8. This completely messed up the linker paths for CMake. To detect this situation already when running cmake we have resorted to first setting the CMAKE_CUDA_FLAGS to force cmake to make nvcc use the host compiler and to activate CUDA (if available) before calling `find_package(CUDA)`. If the host compiler is not supported CMake will error out during `enable(CUDA)` Note that we still use (deprecated) FindCUDA later to determine the libraries to link to. The users has the option to either deactivate CUDA by setting `-DCMAKE_DISABLE_FIND_PACKAGE_CUDA=ON` or to use a compiler supported by nvcc (setting `-DCMAKE_CXX_COMPILER=compiler`). Additionally we do not try to activate CUDA the CMake version is < 3.8. Please note that previously CMake would have errored out here anyway since we used the unsupported `enable_language(CUDA)` even in this case. Closes #2363.
