Is my problem so vague that nobody even has a suggestion? If so, are there
things I can try to answer that might help?
Thanks...

Subject: cmake newbie questions
Disclaimer: I'm new to cmake, and mostly new to make, for that matter (I come
from one of those Other Platforms that don't use make). I'm trying to use a
different C compiler (the Dignus cross-compiler for z/OS) to compile an
existing product on Windows XP. I've installed cmake and GNU make, as well as
the Dignus stuff, and added make and the Dignus stuff to the path.
The Dignus C compiler executable is dcc.exe, in c:\program files\dignus\.
GNU make is make.exe, in c:\program files\GnuWin32\bin.
The Dignus linker is plink.exe, also in c:\program files\dignus\.
My C source is in an svn directory tree; call it c:\Voltage (it's much longer
than that, but).
The C source uses cmake on Linux and on Windows (with Visual Studio .NET 2003)
successfully, but of course that isn't what I'm trying to use.
I've been reading and tinkering with cmake, and it *seems* like it's flexible
enough that this should work. But I'm missing (at least) something fundamental
in my understanding.
If I fire up the cmake GUI, it's very unhappy, which makes sense. But I seem
to be able to flog it into agreeing that it's doing Unix makefile format (as
opposed to defaulting to one of the Visual whatever formats).
If I go to the top of my svn tree (the first level that has a CMakeLists.txt in
it) and run cmake -i, it fails:
====================
Please wait while cmake processes CMakeLists.txt files....
CMake Error at C:/Program Files/CMake
2.6/share/cmake-2.6/Modules/CMakeTestCCompiler.cmake:32 (MESSAGE):
The C compiler "C:/Program Files/Dignus/dcc.exe" is not able to compile a
simple test program.
It fails with the following output:
Change Dir: C:/Voltage/Toolkit/trunk/vtk-core/CMakeFiles/CMakeTmp
Run Build Command:C:\PROGRA~1\GnuWin32\bin\make.exe CMAKE_TRY_COMPILE.dsw /MAKE

make: Nothing to be done for `CMAKE_TRY_COMPILE.dsw'.
make: *** No rule to make target `/MAKE'. Stop.
CMake will not be able to correctly generate this project.
Call Stack (most recent call first):
CMakeLists.txt:16 (project)
====================
As noted, I know I'm missing something very basic here. Can anyone point me in
the right direction? Thanks...!
You should try the nmake or unix makefiles generator, the vs IDE stuff
will not work with different compilers. From a shell that has Dignus C
compiler setup and in your path, set CC=dcc.exe, run cmake, (cmake-gui
or CMakeSetup, or just cmake). See if that helps.
