# NOTE: You can make embree accept custom CXXFLAGS by turning off

# EMBREE_IGNORE_CMAKE_CXX_FLAGS. However, the linking will fail if you use

|
# any "m*" compile flags. This is because embree builds modules for the
|
|
# different supported ISAs and picks the correct one at runtime.
|
|
# "m*" will pull in cpu instructions that shouldn't be in specific modules
|
|
# and it fails to link properly.
