 `-DCMAKE_PREFIX_PATH=...` or per dependency via `-D{DEPENDENCY}_ROOT=...` (`*_ROOT` variables can also be environment variables).
 
-## Installation via Spack
-
-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
-cmake -S fairmq_source -B fairmq_build -GNinja -DCMAKE_BUILD_TYPE=Debug -DBUILD_TESTING=ON
-# develop, compile, test
-spack env deactivate # at end of dev session, or simply close the shell
-```
