There are several methods to influence the search order. cc65 manages two
search lists: One for system header files (delimited by <>) and one for user
includes (delimited by ""). On startup, the search path list for user includes
is initialized by the current directory, while the search list for the system
includes is initialized by "include" and a precompiled value
(/usr/lib/cc65/include for linux). So by using
#include <conio.h>
the compiler will always find the conio.h from the system include directory
first, provided that it is in one of the directories mentioned above (should
be the default on unix systems).
In addition to that, the compiler will add the value of the environment
variable CC65_INC (if it exists) to both search lists, as well as any path
given on the command line with -I. While additional paths are placed into both
lists, you can give them in any order. If you add the cc65 include directory
first, it will find the conio.h there.
So I cannot see why this doesn't work for you. Have you used the correct
include file delimiters and tried changing the order of the -I command line
options?
