+Prerequisite: [Spack](https://spack.readthedocs.io/en/latest/getting_started.html)
+
+```bash
+spack info fairmq # inspect build options
+spack install fairmq # build latest packaged version with default options

+Build FairMQ's dependencies via Spack for development:
+```bash
+git clone -b dev https://github.com/FairRootGroup/FairMQ fairmq_source
+spack --env fairmq_source install # installs deps declared in fairmq_source/spack.yaml
+spack env activate fairmq_source # sets $CMAKE_PREFIX_PATH which is used by CMake to find FairMQ's deps
