-DLEMON_DOC_SOURCE_BROWSER=YES

   Include the browsable cross referenced LEMON source code into the

   doc. It makes the doc quite bloated, but may be useful for

   developing LEMON itself.

 -DLEMON_DOC_USE_MATHJAX=YES

   Use MathJax (http://mathjax.org) for rendering the math formulae in

   the doc.  It of much higher quality compared to the default LaTeX

   generated static images and it allows copy&paste of the formulae to

   LaTeX, Open Office, MS Word etc. documents.

   On the other hand, it needs either Internet access or a locally

   installed version of MathJax to properly render the doc.

 -DLEMON_DOC_MATHJAX_RELPATH=DIRECTORY

   The location of the MathJax library. It defaults to

   http://www.mathjax.org/mathjax, which necessitates Internet access

   for proper rendering. The easiest way to make it usable offline is

   to set this parameter to 'mathjax' and copy all files of the MathJax

   library into the 'doc/html/mathjax' subdirectory of the build

   location.

   See http://docs.mathjax.org/en/latest/installation.html for more details.

 -DLEMON_ENABLE_GLPK=NO

 -DLEMON_ENABLE_COIN=NO

 -DLEMON_ENABLE_ILOG=NO

   Enable optional third party libraries. They are all enabled by default. 

 -DLEMON_DEFAULT_LP=GLPK

   Sets the default LP solver backend. The supported values are

   CPLEX, CLP and GLPK. By default, it is set to the first one which

   is enabled and succesfully discovered.

 -DLEMON_DEFAULT_MIP=GLPK

   Sets the default MIP solver backend. The supported values are

   CPLEX, CBC and GLPK. By default, it is set to the first one which

   is enabled and succesfully discovered.
