# Include path:
The list of directories for header files is often referred to as the include path, a
# Library path
List of directories for libraries as the library search path or link path.
# Modifying these search paths when compiling:
# Where 'gdbm' library is within /opt/gdbm-1.8.3/lib
$ gcc -Wall -I/opt/gdbm-1.8.3/include -L/opt/gdbm-1.8.3/lib dbmain.c -lgdbm

#Environment variables to control the Include:
C_INCLUDE_PATH (for c) and CPLUS_INCLUDE_PATH (for cpp)
