[CMake] Compiler Test Failing on Windows 7

[Smith Jack (Ext. - UGIS - UniCredit Group)]

Do you have a stale CMakeCache.txt file somewhere ?

It's *usually* perfectly safe to delete all occurrences of CMakeCache.txt within a project and have CMake regenerate them.  I say usually, because I have no idea if you are modifying that file for some reason, although the practice is not recommended.

Subject: [CMake] Compiler Test Failing on Windows 7

After upgrading to windows 7, I'm getting errors when trying to run the cmake project generation step.  It seems as though I'm unable to copy a file.  I have the directory as a subdirectory of my users folder, so I didn't think it would be a permissions issue.

Here is the error:
CMake Error: Could not COPY_FILE.

Even though the path says AMD64, it's doing a 32-bit build.  The path is made from a batch script, and cmake is hardcoded to use 32bit on windows in the build scripts.

Any ideas on what the problem might be?

Thanks,
Joe
