   3 # To use: INCLUDE(Gettext)
   4 #
   5 # Most of the gettext support code is from FindGettext.cmake of cmake,
   6 # but it is included here because:
   7 #
   8 # 1. Some system like RHEL5 does not have FindGettext.cmake
   9 # 2. Bug of GETTEXT_CREATE_TRANSLATIONS make it unable to be include in 'All'
  10 # 3. It does not support xgettext
  11 #

  15 #      Default:  --language=C --keyword=_ --keyword=N_ --keyword=C_:1c,2 --keyword=NC_:1c,2
  16 #  GETTEXT_MSGMERGE_EXECUTABLE: the full path to the msgmerge tool.
  17 #  GETTEXT_MSGFMT_EXECUTABLE: the full path to the msgfmt tool.
