Decompose OGS_CONFIG

[norihiro-w]

(Merging of this PR should be waited until #26 and #28 are done.)

Current OGS_CONFIG CMake option supports the following configurations.

• FEM
• SP
• GEMS
• JFNK
• PETSC
• PETSC_GEMS
• IPQC
• PQC
• BRNS
• LIS
• CAP
• MKL
• MPI

These are actually mixtures of geochemical solver and linear solver types, and the mixture results in a lengthy list of configurations if we want to have different combinations of them, e.g. GEMS and PETSC_GEMS.

To simplify this, this PR introduces OGS_LSOLVER and OGS_CHEMSOLVER options. OGS_LSOLVER option supports

• DEFAULT (default setting in a configuration set, see below)
• RF (solver form Rockflow time)
• SP
• PETSC

Additionally OGS_USE_LIS and OGS_USE_MKL are introduced to use either Lis or MKL or both ( SP should be selected in OGS_LSOLVER because data structures in SP are internally used).

OGS_CHEMSOLVER options supports

• DEFAULT (default setting in a configuration set, see below)
• NONE
• GEMS
• IPQC
• PQC
• BRNS
• CAP

After these changes, OGS_CONFIG is used to specify a configuration set. Followings are supported currently:

• FEM: RF + NONE
• SP: SP + NONE
• GEMS: SP + GEMS
• JFNK: SP + JFNK
• PETSC: PETSC
• IPQC: RF + IPQC
• PQC: SP + PQC
• BRNS: SP + BRNS
• CAP: RF + CAP
• LIS: SP + LIS
• MKL: SP + LIS + MKL
• MPI: SP(MPI)
• PETSC: PETSC(MPI)
