Thanks for working on this.

The names should not be changed at all.  They become cache entries
that people may be setting in their scripts on the command line, or
have set in existing build trees.  Also the names are visible to the
human in cmake-gui so calling them "..._FOUND" does not make sense.

The FPHSA component handling still leaves it to the module code to
specify whether each component was found.  Therefore you should just
use a pattern like this:

 find_program(LATEX2HTML_CONVERTER ...)
 if (LATEX2HTML_CONVERTER)
   set(LATEX_LATEX2HTML_FOUND 1)
 else()
   set(LATEX_LATEX2HTML_FOUND 0)
 endif()

Once you have that explicit mapping then you can optionally use
lower-case component names.  I have no strong preference on that
though.

Thanks,
