We've been doing this for almost 4 years, so we're pretty happy with it (other than this new issue).

OK I see I do intend to change your habits just to suggest
that it is usually safer for testing purpose.

You should have a bunch of cmake_install.cmake files (but those
shouldn't change the behaviour of the next cmake run)
You'll probably have CPackConfig.cmake and CPackSourceConfig.cmake
Then any file coming from configure_file or add_custom_command of yours.

OK good.

Ok then may be the ASM usage triggers C compiler setup too early,
again Alex would know better than me here.

Could you try

cmake_minimum_required (VERSION 2.6)
project(ZFPE C)
SET(CMAKE_ALLOW_LOOSE_LOOP_CONSTRUCTS true)
enable_language(ASM_DIGNUS)

instead of your current.

cmake_minimum_required (VERSION 2.6)
project(ZFPE C ASM_DIGNUS)
SET(CMAKE_ALLOW_LOOSE_LOOP_CONSTRUCTS true)

Yes then now we may need your ASM_DIGNUS cmake support file
because unless I'm wrong I do not see it in CMake upstream source.
