#### Optional Spack environment variations
The Spack environment used to build Quandary is defined in `.spack_env/spack.yaml`.
You can add or remove packages from the `specs` list as needed or use different variants of these.
For instance, if you want to use the debug variant (which builds Petsc in debug mode) you can use `quandary@develop+test+debug`.
For instance, if you want to use the debug variant (which builds Quandary and Petsc in debug mode) you can use `quandary@develop+test build_type=Debug`.
To build with `PetscInt`s set to 64-bit integers, use `quandary+int64`.
To use a specific version of Petsc instead of the latest release, you can do e.g. `quandary@develop^petsc@3.22.1`.
The `+test` variant (by default on in `.spack_env/spack.yaml`) adds python and pip to the Spack environment.
This allows `pip install` to install python packages to your Spack virtual environment rather than a global one.

To build in debug mode use `cmake -DCMAKE_BUILD_TYPE=Debug ..`.
Add the path to Quandary to your `PATH` variable with `export PATH=/path/to/quandary/:$PATH`, so your binary can be found.
Alternatively, you can install the Quandary executable in a specific path (such as the default `/usr/local/bin` to have it in your `PATH` automatically):
