[CMake] Where are object files located, and how do I change the default extension?

[Carlson Daniel]

Best CMake users,

I am using CMake in some smaller embedded projects which we have converted
from traditional make scripts. After all c-files has been compiled we want
to perform some tests on the generated object-files. The tests we are
running demands that the object files are denoted myFile.o and not
myFile.c.obj which is the default when running CMake for MinGw.

My questions:

1. How can I change the default extension of an object file? I have tried to
use the CMake variable CMAKE_C_OUTPUT_EXTENSION and set it to e.g. ".o" but
the extension is still ".obj". In the Cmake module
"CMakeCXXInformation.cmake" this variable is set depending on the variabele
"UNIX" and when I test to set the extension in this CMake module to ".foo"
the extension is changed to ".foo". Is it not possible to change the default
extension from my main CMakeList-file?

2. Is there a way to get the path of an object file? What I want to do is to
retreive the output path of an obcject file from a c-file
e.g.appl/CMakeFiles/appl.dir/smhd/ if my c-file resides in appl/smhd/

I am using Cmake 2.6.2 on a Windows machine.

Thanks in advance,

Daniel Carlson
