#
# The following function is defined:
#
# add_latex_document(<tex_file>
# [BIBFILES <bib_files>]
# [INPUTS <input_tex_files>]
# [IMAGE_DIRS] <image_directories>
# [IMAGES] <image_files>
# [CONFIGURE] <tex_files>
# [DEPENDS] <tex_files>
# [MULTIBIB_NEWCITES] <suffix_list>
# [USE_INDEX]
# [INDEX_NAMES <index_names>]
# [USE_GLOSSARY] [USE_NOMENCL]
# [FORCE_PDF] [FORCE_DVI] [FORCE_HTML]
# [EXCLUDE_FROM_ALL]
# [EXCLUDE_FROM_DEFAULTS])
# Adds targets that compile <tex_file>. The latex output is placed
# in LATEX_OUTPUT_PATH or CMAKE_CURRENT_BINARY_DIR if the former is
# not set. The latex program is picky about where files are located,
# so all input files are copied from the source directory to the
# output directory. This includes the target tex file, any tex file
# listed with the INPUTS option, the bibliography files listed with
# the BIBFILES option, and any .cls, .bst, and .clo files found in
# the current source directory. Images found in the IMAGE_DIRS
# directories or listed by IMAGES are also copied to the output
# directory and converted to an appropriate format if necessary. Any
# tex files also listed with the CONFIGURE option are also processed
# with the CMake CONFIGURE_FILE command (with the @ONLY flag). Any
# file listed in CONFIGURE but not the target tex file or listed with
# INPUTS has no effect. DEPENDS can be used to specify generated files
# that are needed to compile the latex target.
#
# The following targets are made:
# name_dvi: Makes <name>.dvi
# name_pdf: Makes <name>.pdf using pdflatex.
# name_safepdf: Makes <name>.pdf using ps2pdf. If using the
# default program arguments, this will ensure all fonts
# are embedded and no lossy compression has been
# performed on images.
# name_ps: Makes <name>.ps
# name_html: Makes <name>.html
# name_auxclean: Deletes <name>.aux and other auxiliary files.
# This is sometimes necessary if a LaTeX error occurs
# and writes a bad aux file. Unlike the regular clean
# target, it does not delete other input files, such as
# converted images, to save time on the rebuild.
#
# Unless the EXCLUDE_FROM_ALL option is given, one of these targets
# is added to the ALL target and built by default. Which target is
# determined by the LATEX_DEFAULT_BUILD CMake variable. See the
# documentation of that variable for more details.
#
# Unless the EXCLUDE_FROM_DEFAULTS option is given, all these targets
# are added as dependencies to targets named dvi, pdf, safepdf, ps,
# html, and auxclean, respectively.
#
# If the argument USE_INDEX is given, then commands to build an index
# are made. If the argument INDEX_NAMES is given, an index file is
# generated for each name in this list. See the LaTeX package multind
# for more information about how to generate multiple indices.
#
# If the argument USE_GLOSSARY is given, then commands to
# build a glossary are made. If the argument MULTIBIB_NEWCITES is
# given, then additional bibtex calls are added to the build to
# support the extra auxiliary files created with the \newcite command
# in the multibib package.
#
# History:
#
# 2.1.1 Support for finding bmp, ppm, and other image files.
#
# 2.1.0 Fix an error where the pdf target and others were defined multiple
# times if UseLATEX.cmake was included multiple times.
#
# Added INDEX_NAMES option to support multiple indexes in a single
# document from the multind package (thanks to Dan Lipsa).
#
# 2.0.0 First major revision of UseLATEX.cmake updates to more recent features
# of CMake and some non-backward compatible changes.
#
# Changed all function and macro names to lower case. CMake's identifiers
# are case insensitive, but the convention moved from all upper case to
# all lower case somewhere around the release of CMake 2. (The original
# version of UseLATEX.cmake predates that.)
#
# Remove condition matching in if statements. They are no longer necessary
# and are even discouraged (because else clauses get confusing).
#
# Use "new" features available in CMake such as list and argument parsing.
#
# Remove some code that has been deprecated for a while.
#
# Mark variables for compiler and converter executables as advanced to
# match the more conventional CMake behavior.
#
# Changed how default builds are specified and add the ability to force
# a particular build.
#
# Made the base targets (pdf, dvi, etc.) global. add_latex_document
# always mangles its target names and these base targets depend on
# the targets with mangled names.
#
# 1.10.5 Fix for Window's convert check (thanks to Martin Baute).
#
# 1.10.4 Copy font files to binary directory for packages that come with
# their own fonts.
#
# 1.10.3 Check for Windows version of convert being used instead of
# ImageMagick's version (thanks to Martin Baute).
#
# 1.10.2 Use htlatex as a fallback when latex2html is not available (thanks
# to Tomasz Grzegurzko).
#
# 1.10.1 Make convert program mandatory only if actually used (thanks to
# Julien Schueller).
#
# 1.10.0 Added NO_DEFAULT and DEFAULT_PS options.
# Fixed issue with cleaning files for LaTeX documents originating in
# a subdirectory.
#
# 1.9.6 Fixed problem with LATEX_SMALL_IMAGES.
# Strengthened check to make sure the output directory does not contain
# the source files.
#
# 1.9.5 Add support for image types not directly supported by either latex
# or pdflatex. (Thanks to Jorge Gerardo Pena Pastor for SVG support.)
#
# 1.9.4 Fix issues with filenames containing multiple periods.
#
# 1.9.3 Hide some variables that are now cached but should not show up in
# the ccmake list of variables.
#
# 1.9.2 Changed MACRO declarations to FUNCTION declarations. The better
# FUNCTION scoping will hopefully avoid some common but subtle bugs.
# This implicitly increases the minimum CMake version to 4.6 (although
# I honestly only test it with the latest 4.8 version).
#
# Since we are updating the minimum CMake version, I'm going to start
# using the builtin LIST commands that are now available.
#
# Favor using pdftops from the Poppler package to convert from pdf to
# eps. It does a much better job than ImageMagick or ghostscript.
#
# 1.9.1 Fixed typo that caused the LATEX_SMALL_IMAGES option to fail to
# activate.
#
# 1.9.0 Add support for the multibib package (thanks to Antonio LaTorre).
#
# 1.8.2 Fix corner case when an argument name was also a variable containing
# the text of an argument. In this case, the CMake IF was matching
# the argument text with the contents of the variable with the same
# argument name.
#
# 1.8.1 Fix problem where ps2pdf was not getting the appropriate arguments.
#
# 1.8.0 Add support for synctex.
#
# 1.7.7 Support calling xindy when making glossaries.
#
# Improved make clean support.
#
# 1.7.6 Add support for the nomencl package (thanks to Myles English).
#
# 1.7.5 Fix issue with bibfiles being copied two different ways, which causes
# Problems with dependencies (thanks to Edwin van Leeuwen).
#
# 1.7.4 Added the DEFAULT_SAFEPDF option (thanks to Raymond Wan).
#
# Added warnings when image directories are not found (and were
# probably not given relative to the source directory).
#
# 1.7.3 Fix some issues with interactions between makeglossaries and bibtex
# (thanks to Mark de Wever).
#
# 1.7.2 Use ps2pdf to convert eps to pdf to get around the problem with
# ImageMagick dropping the bounding box (thanks to Lukasz Lis).
#
# 1.7.1 Fixed some dependency issues.
#
# 1.7.0 Added DEPENDS options (thanks to Theodore Papadopoulo).
#
# 1.6.1 Ported the makeglossaries command to CMake and embedded the port
# into UseLATEX.cmake.
#
# 1.6.0 Allow the use of the makeglossaries command. Thanks to Oystein
# S. Haaland for the patch.
#
# 1.5.0 Allow any type of file in the INPUTS lists, not just tex file
# (suggested by Eric Noulard). As a consequence, the ability to
# specify tex files without the .tex extension is removed. The removed
# function is of dubious value anyway.
#
# When copying input files, skip over any file that exists in the
# binary directory but does not exist in the source directory with the
# assumption that these files were added by some other mechanism. I
# find this useful when creating large documents with multiple
# chapters that I want to build separately (for speed) as I work on
# them. I use the same boilerplate as the starting point for all
# and just copy it with different configurations. This was what the
# separate ADD_LATEX_DOCUMENT method was supposed to originally be for.
# Since its external use is pretty much deprecated, I removed that
# documentation.
#
# 1.4.1 Copy .sty files along with the other class and package files.
#
# 1.4.0 Added a MANGLE_TARGET_NAMES option that will mangle the target names.
#
# Fixed problem with copying bib files that became apparent with
# CMake 2.4.
#
# 1.3.0 Added a LATEX_OUTPUT_PATH variable that allows you or the user to
# specify where the built latex documents to go. This is especially
# handy if you want to do in-source builds.
#
# Removed the ADD_LATEX_IMAGES macro and absorbed the functionality
# into ADD_LATEX_DOCUMENT. The old interface was always kind of
# clunky anyway since you had to specify the image directory in both
# places. It also made supporting LATEX_OUTPUT_PATH problematic.
#
# Added support for jpeg files.
#
# 1.2.0 Changed the configuration options yet again. Removed the NO_CONFIGURE
# Replaced it with a CONFIGURE option that lists input files for which
# configure should be run.
#
# The pdf target no longer depends on the dvi target. This allows you
# to build latex documents that require pdflatex. Also added an option
# to make the pdf target the default one.
#
# 1.1.1 Added the NO_CONFIGURE option. The @ character can be used when
# specifying table column separators. If two or more are used, then
# will incorrectly substitute them.
#
# 1.1.0 Added ability include multiple bib files. Added ability to do copy
# sub-tex files for multipart tex files.
#
# 1.0.0 If both ps and pdf type images exist, just copy the one that
# matches the current render mode. Replaced a bunch of STRING
# commands with GET_FILENAME_COMPONENT commands that were made to do
# the desired function.
#
# 0.4.0 First version posted to CMake Wiki.
