[CMake] Newbie question: cmake does not have nmake generator

[David Aldrich]

Hi Bill and Alan

Thank you both very much for answering my question. I did indeed have an old version of CMake, from a forgotten installation of Cygwin, and that was being invoked. I have now deleted that old CMake (and hopefully Cygwin as well) and am now truly running 2.6.4. 

C:\plplot-5.9.5\buildnmake>cmake --help
cmake version 2.6-patch 4
[snip]

However, I have now hit another problem:

C:\plplot-5.9.5\buildnmake>cmake -G "NMake Makefiles" -DCMAKE_INSTALL_PREFIX=install ..
CMake Error: The source "C:/plplot-5.9.5/CMakeLists.txt" does not match the source "/cygdrive/c/plplot-5.9.5/CMakeLists.
txt" used to generate cache.  Re-run cmake with a different source directory.

Any idea why this is happening please? Is the mention of 'cygdrive' worrying?

Best regards

David
