My problem (the error) already occurs in the toolchain file, this
means before the CMakeLists.txt is read. So far it is total
independent of the entries in the CMakeLists.txt!
I have added the line:
message ("Mein CMakeLists.txt File")
in top of my CMakeLists.txt and would assume that there is an output
on the console with the string, but it isn't.
The output is stopped while parsing the toolchain file and
determining the compiler.

You can use the following commands to know what are compilers used in
the CMakeLists.txt:
message("C compiler: " ${CMAKE_C_COMPILER})
message("C++ compiler: " ${CMAKE_CXX_COMPILER})
Moreover, you can set them:
set(CMAKE_CXX_COMPILER ...)

I'm using CMake in version 2.8.5 and just want to cross compile with a
decicated Compiler / Linker set on my Windows machine. Of course I've
read the FAQ and the Tutorial, afterwards I started trying to use CMake
on a DOS (cmd.exe) command line interface with CMakeLists.txt and a
toolchain file. After all tests failed to get CMake work in the Win32
environment, I tried it in my private Linux (Debian Squeeze) and the
same procedure is successful. In Linux environment it works as
described, in Win32 not.
My PC has installed Windows XP including SP3.
CMake version 2.8.5 is installed.
My development path contains a CMakeLists.txt and a toolchain_ppc.cmake
file, because I want to compile on my WinXP code for an embedded
hardware using a PPC processor.
The toolchain_ppc.cmake file contains the following settings:
set (CMAKE_GENERATOR "NMake Makefiles")
set (CMAKE_SYSTEM_NAME "Generic")
set (CMAKE_C_COMPILER "dcc.exe")
set (CMAKE_SYSTEM_PROCESSOR "ppc")
if(CMAKE_CROSSCOMPILING)
message("Cross Compiling")
endif(CMAKE_CROSSCOMPILING)
set(CMAKE_C_COMPILER "C:/WindRiver/diab/5.9.0.0/WIN32/bin/dcc.exe")
set(CMAKE_C_FLAGS "-tPPCVLEEN:simple")
In my build environment I created an empty folder output and in the
command line interface (console / cmd.exe) I'm calling the cmake tool:
D:\novero\Discovery\impl\target\CarIF_Appl\output>cmake -D
CMAKE_TOOLCHAIN_FILE="..\toolchain_ppc.cmake" ..
The output of the cmake tool always is:
-- Building for: Visual Studio 10
Cross Compiling
As you can see my message "Cross Compiling" is shown, this introduces
that cmake is using the "CMAKE_CROSSCOMPILING" flag. But why the hell is
there always the output "-- Building for: Visual Studio 10"?
I don't wan't to use anything from / for Visual Studio 10.
The CMakeOutput.log contains the following lines:
The target system is: Generic - - ppc
The host system is: Windows - 5.1 - x86

I just want to use a standard Assembler, C Compiler and Linker.
I don't need CXX (C++) in my build environment and even I don't need
(want) any Visual Studio in my Cross Compilation.
The generator for CMake shall be "NMake Makefiles" so that the generated
Makefile can be used with "NMake".
Hopefully you can help me out of this.
