[Cmake] Compililation Errors of CMAKE 1.8 on Mac OSX

[Wolfgang Burgstaller]

Hello all CMAKER's,
Dear support,

there is a strange thing going on my CMake. After having compiled  
successfully the vtk - package I want to build the new release of  
InsightApplication. But having defined Source and Binary directories  
some compilation errors occur..


Compilation errors:
------------------------------------------------------------------------ 
------------------------------

1.) CMake Error: The source "/Developer/VTK/CMake/CMakeLists.txt" does  
not match the source "/usr/local/lib/vtk/CMake/CMakeLists.txt" used to  
generate cache. Re-run cmake with a different source directory.


2.) CMake Error: Internal CMake error, TryCompile configure of cmake  
failed.

3.) failed to compile VTK extensions to CMake


4.) CMake Error: This project requires some variables to be set, and  
cmake can not find them. Please set the following variables:  
OPENGL_INCLUDE_DIR(ADVANCED)


5.) CMake Error: Error in configuration process, project files may be  
invalid

------------------------------------------------------------------------ 
------------------------------

Why does CMake not accept the new settings on where to build the source  
and the binaries?



How can I fix that?


System: Mac OSX 10.2.8
CMake: 1.8 (downloaded (no CVS) and installed over 1.6.7)


Thank you very much for any advise that boost me out of this  problem
