# FindLATEX

Finds LaTeX compiler and Latex-related software like BibTeX. LaTeX is a typesetting system for the production of technical and scientific documentation.

## Components

Added in version 3.2.

Components can be optionally specified using a standard CMake syntax:

    find_package(LATEX [COMPONENTS <component>...])

Supported components are:

`PDFLATEX`

  Finds the PdfLaTeX compiler.

`XELATEX`

  Finds the XeLaTeX compiler.

`LUALATEX`

  Finds the LuaLaTeX compiler.

`BIBTEX`

  Finds the BibTeX compiler.

`BIBER`

  Finds the Biber compiler.

`MAKEINDEX`

  Finds the MakeIndex compiler.

`XINDY`

  Find the xindy compiler.

`DVIPS`

  Finds the DVI-to-PostScript (DVIPS) converter.

`DVIPDF`

  Finds the DVIPDF converter.

`PS2PDF`

  Finds the the PS2PDF converter.

`PDFTOPS`

  Finds the PDF-to-PostScript converter.

`LATEX2HTML`

  Finds the converter for converting LaTeX documents to HTML.

`HTLATEX`

  Finds htlatex compiler.

## Result Variables

This module defines the following variables:

`LATEX_FOUND`

  Boolean indicating whether the LaTex compiler and all its required components are found.

`LATEX_<component>_FOUND`

  Boolean indicating whether the LaTeX `<component>` is found.

## Cache Variables

The following cache variables may also be set:

`LATEX_COMPILER`

  The path to the LaTeX compiler.

`PDFLATEX_COMPILER`

  The path to the PdfLaTeX compiler.

`XELATEX_COMPILER`

  The path to the XeLaTeX compiler.

`LUALATEX_COMPILER`

  The path to the LuaLaTeX compiler.

`BIBTEX_COMPILER`

  The path to the BibTeX compiler.

`BIBER_COMPILER`

  The path to the Biber compiler.

`MAKEINDEX_COMPILER`

  The path to the MakeIndex compiler.

`XINDY_COMPILER`

  The path to the xindy compiler.

`DVIPS_CONVERTER`

  The path to the DVIPS converter.

`DVIPDF_CONVERTER`

  The path to the DVIPDF converter.

`PS2PDF_CONVERTER`

  The path to the PS2PDF converter.

`PDFTOPS_CONVERTER`

  The path to the pdftops converter.

`LATEX2HTML_CONVERTER`

  The path to the LaTeX2Html converter.

`HTLATEX_COMPILER`

  The path to the htlatex compiler.

## Examples

Finding LaTeX in a project:

    find_package(LATEX)

Finding LaTeX compiler and specifying which additional LaTeX components are required for LaTeX to be considered found:

    find_package(LATEX COMPONENTS PDFLATEX)

    if(LATEX_FOUND)
      execute_process(COMMAND ${LATEX_COMPILER} ...)
      execute_process(COMMAND ${PDFLATEX_COMPILER} ...)
    endif()

Or finding LaTeX compiler and specifying multiple components:

    find_package(LATEX COMPONENTS BIBTEX PS2PDF)

    if(LATEXT_FOUND)
      # ...
    endif()
