Codelite from source fails

[Ron Georgia <netverbs%gmail.com@localhost>]

I am trying to build codelite from source but get the failure listed below.
However, clang-c/Index.h is present in /usr/pkg/include/clang-c

$ ls -l /usr/pkg/include/clang-c/Index.h
-rw-r--r--  1 root  wheel  214020 Jul 30  2018 /usr/pkg/include/clang-c/Index.h 

If I change clangpch_cache.h line 35 from 
#include <clang-c/Index.h>
To
#include "/usr/pkg/include/clang-c/Index.h"

The process does move forward to the next reference to  <clang-c/Index.h>
Noob question: 
    is there an environment or make variable that I can set that points the "/usr/pkg/include/" directory?
    CLANG_INCLUDE

I did read through the makefile and the make man page.
