# Usage:
|
|
# Control the search through Matio_DIR or setting environment variable
|
|
# Matio_ROOT to the Matio installation prefix.
|
|
#
|
|
# This module does not search default paths!
|
|
#
|
|
# Following variables are set:
|
|
# Matio_FOUND (BOOL) Flag indicating if Matio was found
|
|
# Matio_INCLUDE_DIR (PATH) Path to the Matio include file
|
|
# Matio_INCLUDE_DIRS (LIST) List of all required include files
|
|
# Matio_LIBRARY_DIR (PATH) Path to the Matio library
|
|
# Matio_LIBRARY (FILE) Matio library
