+# - 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
