Also correlate the other buttons more explicitly to the question asked.

ctests: invert Greek LuaTeX tests

From Jürgen:

  LuaTeX support in polyglossia is still very new and experimental.
  I have this enhancement on the agenda for 2.2, but not for 2.1.

For more details, see:

ctests: invert Indonesian LuaTeX tests

The babel name of Indonesian should be changed from "bahasa"
to "indonesian". This should be done after 2.1 is released so as
to minimize potential problems such as Jürgen's example of
\addto\captionsbahasa{\renewcommand\chaptername{Foo}}

For more info, see:

CMake: allow compile-time C++ flags to be set

For example, one could run CMake as follows:
  cmake -DLYX_CXX_FLAGS_EXTRA="-Werror"

Thanks to Kornel.
Cmake build. Use 2.0.0 git-tag to receive the number of commits.

This number is only used for created package name.
Load the CJK package if requested

The package was not loaded if a the main language was not CJK, the main encoding was non-default and the document had a secondary CJK language.
Fix bug #8727: Text::breakParagraph() was always setting the default
layout, even if the paragraph in question requires plain layout.
Make -userdir available to child processes

Otherwise tex2lyx would not find textclass.lst, and thus TeX import and
paste from LaTeX would not work.

ctests: invert Hungarian LuaTeX tests

Similar to Indonesian LuaTeX support (see 7d705438),
"magyar" is not supported. After 2.1 is released,
the babel name of "magyar" should be changed to
"hungarian" (if others disagree then these tests
still should stay inverted).
ctests: ignore latex8 tests

latex8.sty is obsolete and replaced by IEEEconf.
