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).

Add public target include directories to the cmake targets. Therefore the IncludeList.cmake files are not necessary anymore.
ADapt the export macros in the gks libraries.
Add 3rd/vtk helper cmake macro.
Gorup muparser into 3rd subfolder in visual studio project.
