[CMake] ASM support

[Phil Smith]

You're too generous -- I looked yesterday :-(

Anyway, I've followed those instructions (I think) but it's not working. I'm using ASM_DIGNUS as the assembler name. The ASM_DIGNUS files I've added (shown below) are all in Modules\ (the page is a bit vague on where they should go).

CMakeASM_DIGNUSInformation.cmake:
------------------------
set(ASM_DIALECT _DIGNUS)
include(CMakeASMInformation.cmake)
set(ASM_DIALECT _DIGNUS)
SET(CMAKE_ASM_SOURCE_FILE_EXTENSIONS asm)
SET(CMAKE_ASM_OUTPUT_EXTENSION ".o" )
SET(CMAKE_ASM_COMPILE_OBJECT "<CMAKE_ASM_COMPILER> -o <OBJECT> <SOURCE>")
------------------------

CMakeDetermineASM_DIGNUSCompiler.cmake:
------------------------
set(ASM_DIALECT _DIGNUS)
set(CMAKE_ASM_DIGNUS_COMPILER "rexx.exe cc.rex")
include(CMakeASMInformation)
set(ASM_DIALECT _DIGNUS)
------------------------

CMakeTestASM_DIGNUSCompiler.cmake:
------------------------
set(ASM_DIALECT _DIGNUS)
include(CMakeASMInformation.cmake)
set(ASM_DIALECT _DIGNUS)
------------------------

zosport.cmake (in my build directory):
------------------------
# This is a CMake Toolchain file, required for cross-compiling using
# the Dignus cross-compilers on Windows, compiling for z/OS.

# Tell CMAKE the target system name
SET(CMAKE_SYSTEM_NAME "IBM_ZOS")

# Specify the cross-compilers
SET(CMAKE_C_COMPILER   "rexx.exe" "cc.rex dcc.exe")
SET(CMAKE_CXX_COMPILER "rexx.exe" "cc.rex dcxx.exe")
SET(CMAKE_ASM_DIGNUS_COMPILER "rexx.exe" "cc.rex dcxx.exe")

SET(CMAKE_C_CREATE_STATIC_LIBRARY "DAR -rv <TARGET> <OBJECTS>")

SET(CMAKE_CXX_LINK_EXECUTABLE "plink.exe \"-S$ENV{DIGNUS_PROGRAM}/objs_norent/&M\" <OBJECTS> -o <TARGET>")
SET(CMAKE_C_LINK_EXECUTABLE   "plink.exe \"-S$ENV{DIGNUS_PROGRAM}/objs_norent/&M\" <OBJECTS> -o <TARGET>")
------------------------

Here's the result of running CMake:
------------------------

It's only three weeks old or so.
