Hello Robert, please use the homepage I referenced to find the packages you need. I searched for you last mail but I’m sure you’ll find the packages that provide the headers as well after a little time of searching. Each OS is different and I cannot support users in setting up their system to meet the requirements for gr-inspector.

I have installed the two packages you've included as references (libqwtplot3d-qt4-dev, libqwt-dev). I have two new errors when running cmake, including a missing qwt header file (though as I mentioned, I installed the -dev package). Please see https://pastebin.com/ruz43yTu The header file that is missing is not included in the file list of the packages you linked.
