If you mean "POCL_DEBUG", that means pocl will recognize env variable
POCL_DEBUG and print out various useful information. This has nothing
to do with build type, and I recommend to build pocl with it, as it
really helps with troubleshooting. But you *can* compile pocl without
it.

OTOH, i see "None+Asserts" which is the build type. I'm not sure how
you managed to arrive at "None", as there's some Cmake code to set up
the build type if it's missing, but i highly recommend you to pick one.
I'm guessing "RelWithDebInfo" or "Release" are suitable for Debian.

cmake -DCMAKE_BUILD_TYPE=<build-type>

should do it. It's also possible to fine-tune the flags for each build
type, in case you need it. The defaults IIRC are "-O2 -g -DNDEBUG" for
RWDI and "-O3 -DNDEBUG" for Release.
