How to use tracker with exec task

Hello,

I want to use filetracker with exe task.

I have managed to generate tlog files, how do i feed the, back so dependencies can be tracker?
Here is the command.
Seems the only way is for me to write a custom task.
However writing custom task was a problem when visual studio upgrades. I always have issues with msbuild reference from the previous version after that.

Also i want to be able to split TaskParameter Outputs from the exec file.
I have an executable that generates cpp header and cpp source file based on custom grammer.
This is very common scenario for a domain specific language.

Please advise.
