What does "Detecting CXX compiler ABI info - failed" mean - what is the cause of this error, and how is it fixed?

I try to compile a simple CUDA "Hello World" using CMake on my Mac OSX 10.8.3.
Calling cmake . seems to succeed. Here is my CMakeList.txt:

But calling make afterwards fails with the following error(s):

I googled the shown errors but couldn't find any sufficient answers.
Any ideas why make fails, although cmake succeeded.
Thanks for your help.
The default C compiler in XCode changed to CLang in OS X Lion. CLang is incompatible with nvcc, so you need to change the compiler that nvcc uses for non-cuda (host) code. Adding the following to your CMakeList.txt will work:
if (NOT DEFINED CUDA_HOST_COMPILER AND CMAKE_C_COMPILER_ID STREQUAL "Clang" AND EXISTS /usr/bin/gcc)
set(CUDA_HOST_COMPILER /usr/bin/gcc CACHE FILEPATH "Host side compiler used by NVCC")
message(STATUS "Setting CMAKE_HOST_COMPILER to /usr/bin/gcc instead of ${CMAKE_C_COMPILER}.")
endif()
Adjust the path to gcc if necessary.
If you don't want to change your CMakeLists.txt, it works if you set the environment variable CXX to "gcc" (assuming you don't have any other GCC in your path before the one in /usr/bin).
CMake will pick it up automatically.
When using CMake, I noticed the output messages:
-- The C compiler identification is GNU
-- The CXX compiler identification is GNU
-- Check for working C compiler: /usr/bin/gcc
-- Check for working C compiler: /usr/bin/gcc -- works
-- Detecting C compiler ABI info

-- Check for working CXX compiler: /usr/bin/c++
-- Check for working CXX compiler: /usr/bin/c++ -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
I am just curious about how CMake checks if the compiler works and the ABI information.
You can easily see for yourself. The code is located in CMake modules CMakeDetermineCCompiler.cmake, CMakeDetermineCompilerABI.cmake etc.
You can find these modules in your_cmake_install/share/cmake-2.8/Modules.

I want to use Opencv 2.4.0 (beta2) together with EmguCV and MonoDevelop on my Mac OS X Lion system. But I failed to compile the OpenCV 2.4.0 by Cmake and it shows lacking of some dylib files of highgui.
Anybody can tell me the whole configuration and process to compile OpenCV 2.4.0 in Mac OS X? Thanks.
To eliminate the error concerning the sphinx package for python, install it using
sudo easy_install -U Sphinx
OR if you use MacPorts:
sudo port install py26-sphinx
Before check the version of the default python interpreter "python --version". In my example it is 2.6.
I downloaded OpenCV 2.4.0 sources from the repository (rev 8301) and I had no problems compiling it on Mac OS X 10.7.3:
