This repository provides different algebra plugins with minimal functionality for the R&D projects detray and traccc.

To build it standalone, run e.g.

git clone https://github.com/acts-project/algebra-plugins.git
cmake -DCMAKE_BUILD_TYPE=Release -S algebra-plugins -B algebra-plugins-build
cmake --build algebra-plugins-build

Available options:

• ALGEBRA_PLUGINS_CUSTOM_SCALARTYPE: Scalar value type (float or double, double by default)
• ALGEBRA_PLUGINS_INCLUDE_<XXX>: Boolean to turn on/off the build of one of the following plugins:
  • EIGEN: Plugin using Eigen (OFF by default)
  • SMATRIX: Plugin using Smatrix (OFF by default)
  • VC: Plugin using Vc (OFF by default)
  • VECMEM: Plugin using VecMem (OFF by default)
• ALGEBRA_PLUGINS_SETUP_<XXX>: Boolean to turn on/off the explicit "setup" of the externals (GOOGLETEST, EIGEN3, VC and VECMEM)
• ALGEBRA_PLUGINS_USE_SYSTEM_<XXX>: Boolean configuring how to set up a given external
  • ON: The external is searched for "on the system" using find_package;
  • OFF: The package is set up for build as part of this project, using FetchContent.
• ALGEBRA_PLUGINS_BUILD_TESTING: Turn the build/setup of the unit tests on/off (ON by default)
