# Build instructions

Run the scripts in the 'install_external_libs' folder then:
Sparselizard depends on mandatory and optional external libraries.

On debian Linux, run
```sudo apt-get install -y libopenblas-dev libmetis-dev libopenmpi-dev libmumps-dev petsc-dev slepc-dev libgmsh-dev```
or
run the scripts in the 'install_external_libs' folder to download and install these libraries locally.

Then:
```bash
mkdir build && cd build
cmake ..
cmake --build . -j$(nproc)
mkdir build; cmake -B build .; cd build && make -j 4
```

---

To provide a custom path to the petsc, gmsh (optional) or mpi (optional) folder use:
```bash
cmake .. -DPETSC_PATH=/yourpath/petsc -DGMSH_PATH=/yourpath/gmsh -DMPI_PATH=/yourpath/mpi
cmake -B build . -DPETSC_PATH=/yourpath/petsc -DGMSH_PATH=/yourpath/gmsh -DMPI_PATH=/yourpath/mpi
```

It may be convenient to use the cmake GUI:
