Well, neither i get what you meant. cmake generated .cbp file, i opened it. Are you saying that now i can't control what directories compiler will search for headers?
No, we are saying you need to learn to use the Makefile system to do that fix.
Or, convert your program to use the Code::Blocks native build system; this may be simple to very hard to do, Depending on the complexity and size of your application/library.
Note: I suggest reading what options can be passed to make command using the makefile to solve this problem and after finding the options; ask where in Code::Blocks the make options can be placed.
Edit: What I personally would do would be to create an new makefile that uses the CMake generated top makefile and inside my new makefile I would do all the changes needed to fix problems like you are having. But, this requires knowing how to write simple to moderately complex makefiles. I would then change C::B to use my new makefile.
