|
|
# - Find PTSCOTCH include dirs and libraries
|
|
# Use this module by invoking find_package with the form:
|
|
# find_package(PTSCOTCH
|
|
# [REQUIRED] # Fail with error if ptscotch is not found
|
|
# [COMPONENTS <comp1> <comp2> ...] # dependencies
|
|
# )
|
|
#
|
|
# PTSCOTCH depends on the following libraries:
|
|
# - Threads
|
|
# - MPI
|
|
#
|
|
# COMPONENTS can be some of the following:
|
|
# - ESMUMPS: to activate detection of PT-Scotch with the esmumps interface
|
|
#
|
|
# This module finds headers and ptscotch library.
|
|
# Results are reported in variables:
|
|
# PTSCOTCH_FOUND - True if headers and requested libraries were found
|
|
# PTSCOTCH_LINKER_FLAGS - list of required linker flags (excluding -l and -L)
|
|
# PTSCOTCH_INCLUDE_DIRS - ptscotch include directories
|
|
# PTSCOTCH_LIBRARY_DIRS - Link directories for ptscotch libraries
|
|
# PTSCOTCH_LIBRARIES - ptscotch component libraries to be linked
|
|
# PTSCOTCH_INCLUDE_DIRS_DEP - ptscotch + dependencies include directories
|
|
# PTSCOTCH_LIBRARY_DIRS_DEP - ptscotch + dependencies link directories
|
|
# PTSCOTCH_LIBRARIES_DEP - ptscotch libraries + dependencies
|
|
# PTSCOTCH_INTSIZE - Number of octets occupied by a SCOTCH_Num
|
|
#
|
|
# The user can give specific paths where to find the libraries adding cmake
|
|
# options at configure (ex: cmake path/to/project -DPTSCOTCH=path/to/ptscotch):
|
|
# PTSCOTCH_DIR - Where to find the base directory of ptscotch
|
|
# PTSCOTCH_INCDIR - Where to find the header files
|
|
# PTSCOTCH_LIBDIR - Where to find the library files
|
|
# The module can also look for the following environment variables if paths
|
|
# are not given as cmake variable: PTSCOTCH_DIR, PTSCOTCH_INCDIR, PTSCOTCH_LIBDIR
