Correct way to build debian using Cmake and catkin? - cmake

Question

I'm trying to build a debian using CMake/Cpack but am running into an issue. The problem is that I am getting unwanted files in my debian. It is caused by including a subdirectory, which contains a CMakeLists.txt that invokes catkin commands for ROS msg generation.
If I look at the contents of the debian I see generated header files in /usr/include/ and message files in /usr/share. But I only want my debian to have the files in /opt/bin which I specified using install().
Below is a simplified example. If I run the following commands:
mkdir build
cd build
cmake ..
make
cpack
The result is a deb package containing /opt/my-pkg/bin/main (which is great), but it also contains several files in /usr/local, /usr/lib, /usr/share that I don't want to be in the debian. I'm sure there must be a way using CMake/CPack to only create a debian with the specific files I want, but I'm not sure how to do it.
