Module doxygen does not clean all generated files
For the following CMake configuration, the docs
target generated folders html and xml in the build directory.
find_package(Doxygen)
if (DOXYGEN_FOUND)
set(DOXYGEN_GENERATE_HTML YES)
set(DOXYGEN_GENERATE_XML YES)
doxygen_add_docs(docs)
endif()
However when invoking the clean target, only the html folder is deleted. The xml folder is not.
Note - cmake version is 3.16.3
