# Try to find Libexecinfo functionality
# Once done this will define

#  LIBEXECINFO_FOUND - system has Libexecinfo
#  LIBEXECINFO_INCLUDE_DIR - Libexecinfo include directory
#  LIBEXECINFO_LIBRARIES - Libraries needed to use Libexecinfo
#
# 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).
