Moved the custom version to a temporary version and fall back to the version shipped with cmake. This probably breaks the pot-update target which will be fixed later.

# - 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_MSGCAT_EXECUTABLE = msgcat tool
|
|
# GETTEXT_MSGCONV_EXECUTABLE = msgconv 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
|
|
# the cache variables.
