Environnement settings

On Centos, enable devtoolset-10 and rh-git227 and load mpi module:

scl enable devtoolset-10 bash
source /opt/rh/rh-git227/enable
module load mpi

Configure build with CMake

Remember to set -DCMAKE_PREFIX_PATH to the path of the dependencies if using pre-built dependencies.

The first time vcpkg will download and compile all dependencies. This can take a long time. Especially openmpi. Unless some dependencies are updated, nothing will be done on the next build. VCPKG store sources in a cache folder, removing your build folder will only remove the compiled dependencies. Meaning later builds will be faster than the first one even if you remove your build folder

=== "Windows"

```
cmake -B _build -S . -DCMAKE_TOOLCHAIN_FILE=vcpkg/scripts/buildsystems/vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-windows
```

=== "Centos"

```
cmake3 -B _build -S . -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=vcpkg/scripts/buildsystems/vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-linux-release
```

=== "Ubuntu"

```
cmake -B _build -S . -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=vcpkg/scripts/buildsystems/vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-linux-release
```

Here is a list of available CMake configure options:

Option	Default	Description

```

=== "Centos"
