[CMake] FW: cmake newbie questions

[Phil Smith]

Nope, that didn't do it.  I tried it with and without double quotes around the value: no -fascii was passed in either case.  However, I'm tentatively declaring victory (very tentatively -- I've had it working before, but for the wrong reasons, such as NOT doing a linkedit and having it happen to find the "magic string" in the object -- but that's not safe, it could be broken across 80-byte records).

I notice that it's creating what looks like it might be a duplicate set of directories:

CMakeFiles\CMakeTmp\CMakeFiles\cmTryCompileExec.dir

Does it really mean to do that, or is it intending to have just
CMakeFiles\cmTryCompileExec.dir
?  It works, so perhaps machs nicht, but it looked odd to me.

Try that in your toolchain file:
SET(CMAKE_C_COMPILER    c:/progra~1/dignus/cc.bat -fasciiout)
SET(CMAKE_CXX_COMPILER  c:/progra~1/dignus/cxx.bat -fasciiout)

Modules/CMakeDetermineC[XX]Compiler.cmake checks whether there is an
additional argument given and this should be used then, at least for the
first test where it tries to build a basic executable.
