OK, next issue. I'm following (or trying to) the cross-compiler page. Since
the same source tree is to be used to generate Win32 and z/OS, I think I want
to tell it "This is a z/OS run" using a flag. I thus created zcmake.bat:
cmake -DCMAKE_TOOLCHAIN_FILE:string="zos.cmake"
-DCMAKE_GENERATOR:internal="Unix Makefiles"
The reason for the second -D is because otherwise it seemed to assume Visual
Studio no matter what. And since Visual Studio *is* correct when building
Win32, I don't want to change the CMakeLists.txt.
zos.cmake contains (comments removed):
SET(CMAKE_SYSTEM_NAME ZOS)
SET(CMAKE_C_COMPILER "cc.bat")
SET(CMAKE_CXX_COMPILER "cxx.bat")
"zcmake ." produces these errors:

Three issues:
1) Obviously I'm back to having implicit paths, some of which get expanded to
contain embedded blanks. I would like to understand how to overcome this,
although one answer, of course, is to reinstall cmake in a directory that
*doesn't* contain blanks. The various "CMAKE_xxxxx_PATH" variables that are
documented aren't obviously the answer, which doesn't meant they aren't
*actually* the answer.
2) The messages:
-- The C compiler identification is unknown
-- The CXX compiler identification is unknown
...seem to be generated because CMakeCXXCompilerId.cpp.in doesn't know about
Dignus. Is there a nice way to override that? I guess I *could* just document
that "you'll get this message"...
3) System is unknown to cmake, create:
Platform/ZOS to use this system, please send your config file to [EMAIL
PROTECTED] so it can be added to cmake
I kind of grok this in principle, but "create Platform/ZOS" doesn't mean
anything to me, and I don't see it in the Wiki, the book, or Googling for what
seem like the plausible strings.
Here's the especially interesting bit: after all that complaining, if I rerun
zcmake, I get:

That *looks* like it worked?!?!

This really sounds like a cross compiler. In which case you should look
