I tried to build paddle/majel in following steps:

cd ~/work/paddle
git checkout develop
git pull
docker build -t paddle:dev .
docker run --rm -it -v $PWD:/paddle paddle:dev /bin/bash

Then in the development container:

cd /paddle/build
rm CMakeCache*
cmake -DCUDNN_ROOT=/usr/ ..
make -j10 float16_test

where float16_test is a newly added module in paddle/majel/float16_test.cu.

This modules doesn't depend on any other part of Paddle. But the above make command builds Paddle before it builds float16_test. I got log messages include the following:
