[CMake] Problem with ASM and COMPILE_DEFINITIONS

[Marcel Loose]

Hi Torsten,

Thanks for the info, but CMake 2.6.4 doesn't solve my problem.
I must be doing something wrong, but I haven't found out yet what
exactly. I'll continue digging.

Best regards,
Marcel Loose.

Hello Marcel,

you've stumpled on a bug in CMake 
<http://www.cmake.org/Bug/view.php?id=8107>, which has been fixed in 
CMake 2.6.4.

Best regards,

Torsten
