# 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).
