Build cleanly without warnings

[photon-schiesser]

On Linux, run the following build commands:

cmake -Bbuild/
make mk_build_compute

I get the following warnings:

[ 30%] Building CXX object src/CMakeFiles/kompute.dir/OpAlgoDispatch.cpp.o

/home/kompute/src/OpMemoryBarrier.cpp:2:9: warning: #pragma once in main file

      |         ^~~~

These two above warnings seem pretty clear. Can the offending lines be removed?

The below warning is very cryptic to me:

Thanks for opening this issue @ScheissSchiesser 👍

Reopening as we can approach by adding set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Werror -Wall -Wextra") on the CmakeLists.txt
