  11. # - Find PASTIX include dirs and libraries
  12. # Use this module by invoking find_package with the form:
  13. # find_package(PASTIX
  14. # [REQUIRED] # Fail with error if pastix is not found
  15. # [COMPONENTS <comp1> <comp2> ...] # dependencies
  16. # )
  17. #
  18. # PASTIX depends on the following libraries:
  19. # - Threads, m, rt
  20. # - MPI
  21. # - HWLOC
  22. # - BLAS
  23. #
  24. # COMPONENTS are optional libraries PASTIX could be linked with,
  25. # Use it to drive detection of a specific compilation chain
  26. # COMPONENTS can be some of the following:
  27. # - MPI: to activate detection of the parallel MPI version (default)
  28. # it looks for Threads, HWLOC, BLAS, MPI and ScaLAPACK libraries
  29. # - SEQ: to activate detection of the sequential version (exclude MPI version)
  30. # - STARPU: to activate detection of StarPU version
  31. # it looks for MPI version of StarPU (default behaviour)
  32. # if SEQ and STARPU are given, it looks for a StarPU without MPI
  33. # - STARPU_CUDA: to activate detection of StarPU with CUDA
  34. # - STARPU_FXT: to activate detection of StarPU with FxT
  35. # - SCOTCH: to activate detection of PASTIX linked with SCOTCH
  36. # - PTSCOTCH: to activate detection of PASTIX linked with SCOTCH
  37. # - METIS: to activate detection of PASTIX linked with SCOTCH
  38. #
  39. # This module finds headers and pastix library.
  40. # Results are reported in variables:
  41. # PASTIX_FOUND - True if headers and requested libraries were found
  42. # PASTIX_LINKER_FLAGS - list of required linker flags (excluding -l and -L)
  43. # PASTIX_INCLUDE_DIRS - pastix include directories
  44. # PASTIX_LIBRARY_DIRS - Link directories for pastix libraries
  45. # PASTIX_LIBRARIES - pastix libraries
  46. # PASTIX_INCLUDE_DIRS_DEP - pastix + dependencies include directories
  47. # PASTIX_LIBRARY_DIRS_DEP - pastix + dependencies link directories
  48. # PASTIX_LIBRARIES_DEP - pastix libraries + dependencies
  49. #
  50. # The user can give specific paths where to find the libraries adding cmake
  51. # options at configure (ex: cmake path/to/project -DPASTIX_DIR=path/to/pastix):
  52. # PASTIX_DIR - Where to find the base directory of pastix
  53. # PASTIX_INCDIR - Where to find the header files
  54. # PASTIX_LIBDIR - Where to find the library files
  55. # The module can also look for the following environment variables if paths
  56. # are not given as cmake variable: PASTIX_DIR, PASTIX_INCDIR, PASTIX_LIBDIR
