I haven't done it myself, but How about using emacs?  An emacs daemon
could notice when files change and call emacs org-mode functions
(optionally via a call to CMake) to call Matlab to regenerate the plots,
then org-mode export as LaTeX.

A part of CMakeLists.txt to call emacs function may be like this:

add_custom_command(
              OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/mainThesis.tex
              COMMAND emacs -Q --batch --eval \"(progn
                  (add-to-list 'load-path
                         (expand-file-name \\"~/.emacs.d/plugins/org-mode/lisp/\\"))
                  (require 'org)
                  .....etc.

A cron job to download the data locally (using curl or wget) then the
emacs daemon could monitor those also.

Emacs Org-mode source blocks store a hash so they only re-run if
necessary.
