# - Try to find mad
# You can set MAD_ROOT to specify a certain directory to look in first.
# Once done this will define
#  MAD_FOUND - System has mad
#  MAD_INCLUDE_DIRS - The mad include directories
#  MAD_LIBRARIES - The libraries needed to use mad
# Unless we are unable to find ZLIB
# It also adds an imported target named `3ds::mad`, Linking against it is
# equivalent to:
# target_link_libraries(mytarget ${MAD_LIBRARIES})
# target_include_directories(mytarget PRIVATE ${MAD_INCLUDE_DIRS})
