# - Find Gettext run-time library and tools.
# This module finds the GNU gettext run-time library (LGPL), include paths and
# associated tools (GPL). This code sets the following variables:
# GETTEXT_INCLUDE_DIR = path(s) to gettext's include files
# GETTEXT_LIBRARIES = the libraries to link against to use gettext
# GETTEXT_INTL_LIBRARY = path to gettext's intl library
# GETTEXT_RUNTIME_FOUND = true if runtime libs were found (intl)
# GETTEXT_INFO_MSG = information string about gettext
# GETTEXT_XGETTEXT_EXECUTABLE = xgettext tool
# GETTEXT_MSGINIT_EXECUTABLE = msginit tool
# GETTEXT_MSGMERGE_EXECUTABLE = msgmerge tool
# GETTEXT_MSGCAT_EXECUTABLE = msgcat tool
# GETTEXT_MSGCONV_EXECUTABLE = msgconv tool
# GETTEXT_MSGFMT_EXECUTABLE = msgfmt tool
# GETTEXT_TOOLS_FOUND = true if all the tools were found
# GETTEXT_FOUND = true if both runtime and tools were found
# As a convenience, the following variables can be set before including
# this module to make its life easier:
# GETTEXT_SEARCH_PATH = list of path to search gettext components for
# --------------------------------------------------------------------------
# As a convenience, try to find everything as soon as we set any one of
