# The following MACROS are defined:
#
# ADD_LATEX_DOCUMENT(<tex_file>
#                       [BIBFILES <bib_files>]
#                       [INPUTS <input_tex_files>]
#                       [IMAGE_DIRS] <image_directories>
#                       [IMAGES] <image_files>
#                       [CONFIGURE] <tex_files>
#                       [USE_INDEX] [DEFAULT_PDF])
#       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 coverted 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.
#
#       The following targets are made:
#               dvi: Makes <name>.dvi
#               pdf: Makes <name>.pdf using pdflatex.
#               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.
#               ps: Makes <name>.ps
#               html: Makes <name>.html
#               auxclean: Deletes <name>.aux.  This is sometimes necessary
#                       if a LaTeX error occurs and writes a bad aux file.
#
#       If the argument USE_INDEX is given, then commands to build an index
#       are made.
#
# ADD_LATEX_TARGETS(<tex_file>
#                       [BIBFILES <bib_files>]
#                       [INPUTS <input_tex_files>]
#                       [IMAGE_DIRS] <image_directories>
#                       [IMAGES] <image_files>
#                       [CONFIGURE] <tex_files>
#                       [USE_INDEX] [DEFAULT_PDF])
#       Like ADD_LATEX_DOCUMENT, except no files are configured or copied.
#       The files are assumed to already be added to the output directory.
#       This varient is helpful if one set of latex files makes different
#       varients of documents.  For example, with building chapters
#       separately from the entire document.
#
# History:
#
# 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.
