# Try to find Pthread functionality
# Once done this will define
#
# PTHREAD_FOUND - system has Pthread
# PTHREAD_INCLUDE_DIR - Pthread include directory
# PTHREAD_LIBRARIES - Libraries needed to use Pthread
#
# TODO: This will enable translations only if Gettext functionality is
# present in libc. Must have more robust system for release, where Gettext
# functionality can also reside in standalone Gettext library, or the one
# embedded within kdelibs (cf. gettext.m4 from Gettext source).
