Switch to rabs according to version 5.1.1 tag (https://github.com/KarypisLab/METIS/blob/v5.1.1-DistDGL-v0.5/libmetis/balance.c)

 - metis: do not pass -O3 flag on msvc compiler, as this flag is ignored anyway. Instead of /w pass w0, which is equivalent to /w.
 - RheologyK17LBMKernel: A and B are also defined in D3Q27System.h. Therefore to not hide this declaration they are renamed to A_ and B_
 - additional small clean ups...

Changed in metis CMakeLists:
  - add cmake required version to 3.0
  - removed installation
  - add METIS options for idx54 and real64 bit.
  - set target include path
  - set public target defintions
  - put metis target into the 3rd folder group.

Fix exclude in cmake target files.

Update cmake to dev version.

Make use of the new cmake command: target_link_options, target_compile_options and target_compile_definitions.

Therefore the muparser cmakeLists.txt was used, but a modified:
 - name is corresponding to the original file: muparser (in lowercases)
 - removed the install
 - adds public include directory : CMAKE_CURRENT_SOURCE_DIR/include.  --> also adapt the include from the dependent fles.
 - adds link to OpemMP

CXX 11 is now required. (CMake throws an error if cpp11 is not available).
