Find LaTeX

This module finds an installed LaTeX and determines the location
of the compiler.  Additionally the module looks for Latex-related
software like BibTeX.

.. versionadded:: 3.2
  Component processing; support for htlatex, pdftops, Biber, xindy, XeLaTeX,
  LuaLaTeX.

This module sets the following result variables::

  LATEX_FOUND:          whether found Latex and requested components
  LATEX_<component>_FOUND:  whether found <component>
  LATEX_COMPILER:       path to the LaTeX compiler
  PDFLATEX_COMPILER:    path to the PdfLaTeX compiler
  XELATEX_COMPILER:     path to the XeLaTeX compiler
  LUALATEX_COMPILER:    path to the LuaLaTeX compiler
  BIBTEX_COMPILER:      path to the BibTeX compiler
  BIBER_COMPILER:       path to the Biber compiler
  MAKEINDEX_COMPILER:   path to the MakeIndex compiler
  XINDY_COMPILER:       path to the xindy compiler
  DVIPS_CONVERTER:      path to the DVIPS converter
  DVIPDF_CONVERTER:     path to the DVIPDF converter
  PS2PDF_CONVERTER:     path to the PS2PDF converter
  PDFTOPS_CONVERTER:    path to the pdftops converter
  LATEX2HTML_CONVERTER: path to the LaTeX2Html converter
  HTLATEX_COMPILER:     path to the htlatex compiler

Possible components are::

  PDFLATEX
  XELATEX
  LUALATEX
  BIBTEX
  BIBER
  MAKEINDEX
  XINDY
  DVIPS
  DVIPDF
  PS2PDF
  PDFTOPS
  LATEX2HTML
  HTLATEX

Example Usages::
