# Find MathJax package (version 2).
#
# A hint can be provided by defining MATHJAX2_ROOT
# (will succeed if ${MATHJAX2_ROOT}/MathJax.js is found).
#
# Alternatively, a path can be provided in MATHJAX2_USE_ROOT
# so that ${MATHJAX2_USE_ROOT}/MathJax.js is used without
# checking its existence.
# This path could be a URL, an absolute local path or
# a path relative to the generated HTML folder.
#
# Note that version 2 and 3 are incompatible
# and doxygen requires version 2.
# See: https://github.com/doxygen/doxygen/issues/7346
#
# Defined variables:
#  - MATHJAX2_FOUND     - True if MathJax found
#  - MATHJAX2_JS_PATH   - Path to MathJax.js file
#  - MATHJAX2_PATH      - Path to the MathJax root directory
