+# - Find PThread
+# This module finds an installed PThread using the variable PTHREAD_ROOT_DIR 
+# as a lookup path.
+# It sets the following variables:
+#  PTHREAD_FOUND       - set to true if PThread is found
+#  PTHREAD_INCLUDE_DIR - the directory where the include files are located
+#  PTHREAD_LIBRARY     - the path to PThread library
+#
+# The file "pthread.h" is looked for PTHREAD_INCLUDE_DIR.
+# Libraries are searched with following names: 
+#    pthread
+# On Win32:
+#    pthreadVSE2 pthreadVC2
+# or in Debug mode:
+#    pthreadVSE2d pthreadVC2d
+#
