Convert a few Makefiles to a Codeblocks project

I have a C++ project that builds and runs perfectly using makefiles on Ubuntu18.04 and 20.04. I want to start using an Code::Blocks IDE to build, and more importantly, debug the project. I have already added all the C++ files by observing what files are built by the makefile. I am now getting some compilation errors related to headers which I cannot work out how to do. I should point out these are not beginner level issues to fix and I do have experience with C (not C++). As an example I am getting the following error in [login to view URL] error pfont has not been declared searching for pfont i hpp files gives me 5 slightly different header files called [login to view URL] in 5 different folders No doubt someone experienced with GNU makefiles can work out what is supposed to happen. I can provide to the full buildable (via make) project and partly buildable Code::Blocks cbp. I need to be able to build and run the project for completion.
