caoyifeng001 already asked about the -mfpu=neon issue:

#61

His thread was most likely closed because the solution can be found with a simple search and has been fixed in a stranded pull request:

#21

Just adapt the CMakeList.txt according to that pull request and it should all work. Not sure if that will fix the BRISK issue too, but it will pull in a different version of it, so it might work differently.

just delete it .

This CMakeLists.txt file should work on a TX2. It is necessary to use OpenCV2 for it to work though otherwise you run into this bug #65.
