Turn off class graph generation when dot not found
This MR addresses issue #242 (closed), setting a variable in cmake/Doxygen.cmake
that determines whether the dot
command is found or not. The variable is set to YES or NO and the value is then added into the Doxyfile
generated from Doxyfile.in
, setting the HAVE_DOT
and CLASS_GRAPH
parameters within that file to YES
or NO
.
