C++ includes not found but added in CMakeLists.txt

I am currently having trouble with compiling using make. Upon using the command it only builds to 50% before receiving an error shown below.

[ 50%] Building CXX object CMakeFiles/laminar.dir/laminar.o/home/uqslines/Documents/Laminar/laminar.cpp:25:34: fatal error: mechsys/adlbm/Domain.h: No such file or directory compilation terminated.

The directory and file is there, in my .cpp file its directed there via: 

#include <mechsys/adlbm/Domain.h>

I have tried changing the format to see if that resolves the problem and I have tried compiling numerous files as I have multiple examples to test.

I'm fairly new to this, so if anyone has some idea of how I might be able to fix this issue your help would be much appreciated, I've checked the forums and have been unable to find an answer that works.

Try using quotes instead. 

    #include "mechsys/adlbm/Domain.h"

The difference is in the location where the preprocessor searches for the included file.

For #include "filename" the preprocessor searches in the same directory as the file containing the directive. This method is normally used to include programmer-defined header files.

For #include the preprocessor searches in an implementation dependent manner, normally in search directories pre-designated by the compiler/IDE. This method is normally used to include standard library header files.

clang 7.0.2 actually gives you more useful errors

 main.cpp:9:10: error: 'mechsys/adlbm/Domain.h' file not found with <angled> include; use "quotes" instead
