[CMake] ASM support

[Phil Smith]

Yes, that was it. Thank you. I had hacked it into working by just setting CMAKE_ASM_COMPILER, but that was clearly a hack.

One nit that I did have to work around: it doesn't seem to support operands on the compiler name, though in trolling through code trying to understand what I'd done wrong, I saw things that looked like they might have been trying to.

IOW, if I:

SET(CMAKE_ASM${ASM_DIALECT}_COMPILER_INIT "rexx.exe" "cc.rex dasm.exe")

then CMake works, but invokes rexx.exe without the "cc.rex dasm.exe" parameters. It happens that I can work around this for my application, but since it works in a toolchain file:

SET(CMAKE_C_COMPILER   "rexx.exe" "cc.rex dcc.exe")
SET(CMAKE_CXX_COMPILER "rexx.exe" "cc.rex dcxx.exe")

it seems like it should here (for varying values of "should").

I'd offer some updates to http://www.kwwidgets.org/Wiki/CMake/Assembler to help others avoid my idiocy if you're interested.

I think this should be:

SET(CMAKE_ASM_DIGNUS_COMPILE_OBJECT "<CMAKE_ASM_DIGNUS_COMPILER> -o <OBJECT>
  <SOURCE>")
