 ParMETIS is an MPI-based library for partitioning graphs, partitioning finite element meshes,
 and producing fill reducing orderings for sparse matrices. The algorithms implemented in
 ParMETIS are based on the multilevel recursive-bisection, multilevel k-way, and multi-constraint

 git clone https://github.com/KarypisLab/ParMETIS.git
 ```
 
-## Building the ParMETIS library
 
 To build ParMETIS you can follow the instructions below:
 
-### Dependencies
-
-General dependencies for building ParMETIS are: gcc, cmake, build-essential, and an MPI library.
-In Ubuntu systems these can be obtained from the apt package manager (e.g., apt-get install cmake, mpich, etc)
-
-```
-sudo apt-get install build-essential
-sudo apt-get install cmake
-```
-
-In addition, you need to download and install
-[GKlib](https://github.com/KarypisLab/GKlib) and
-[METIS](https://github.com/KarypisLab/METIS) by following the instructions there.
-
-
-### Building and installing ParMETIS
-
-ParMETIS is primarily configured by passing options to make config. For example:
-
-```
-make config cc=mpicc prefix=~/local
-make install
-```
-
-will configure ParMETIS to be built using mpicc and then install the binaries, header files, and libraries at
-
+```sh
+cmake --workflow --preset default
 ```
-~/local/bin
-~/local/include
-~/local/lib
-```
-
-directories, respectively.
-
-### Common configuration options are:
-
-    cc=[compiler]     - The C compiler to use [default is determined by CMake]
-    shared=1          - Build a shared library instead of a static one [off by default]
-    prefix=[PATH]     - Set the installation prefix [~/local by default]
-    gklib_path=[PATH] - Set the prefix path where GKlib has been installed. You can skip
-                        this if GKlib's installation prefix is the same as that of ParMETIS.
-    metis_path=[PATH] - Set the prefix path where METIS has been installed. You can skip
-                        this if METIS' installation prefix is the same as that of ParMETIS.
-
-### Advanced debugging related options:
-
-    gdb=1           - Build with support for GDB [off by default]
-    debug=1         - Enable debugging support [off by default]
-    assert=1        - Enable asserts [off by default]
-    assert2=1       - Enable very expensive asserts [off by default]
-
-### Other make commands
-
-    make uninstall
-         Removes all files installed by 'make install'.
 
-    make clean
-         Removes all object files but retains the configuration options.
 
-    make distclean
-         Performs clean and completely removes the build directory.
