Answer 1

Below changes worked fine for me:

1. Set the path in PATH : C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin

2. Clear cmake cache

3. cmake --help

   The following generators are available on this platform:

   Visual Studio 14 2015 [arch] = Generates Visual Studio 2015 project files. Optional [arch] can be "Win64" or "ARM".

   Visual Studio 12 2013 [arch] = Generates Visual Studio 2013 project files. Optional [arch] can be "Win64" or "ARM".

   Visual Studio 11 2012 [arch] = Generates Visual Studio 2012 project files. Optional [arch] can be "Win64" or "ARM".

   Visual Studio 10 2010 [arch] = Generates Visual Studio 2010 project files. Optional [arch] can be "Win64" or "IA64".

   Visual Studio 9 2008 [arch] = Generates Visual Studio 2008 project files. Optional [arch] can be "Win64" or "IA64".

   Visual Studio 8 2005 [arch] = Generates Visual Studio 2005 project files. Optional [arch] can be "Win64".

   Visual Studio 7 .NET 2003 = Generates Visual Studio .NET 2003 project files.

   Visual Studio 7 = Deprecated. Generates Visual Studio .NET 2002 project files.

   Visual Studio 6 = Deprecated. Generates Visual Studio 6

Used exactly same as above list which was Visual Studio 11 2012

cmake -G "Visual Studio 11 2012" ..\..\source && cmake-gui ..\..\source

Built fine.

Answer 2

1. Remove Cmake cache
2. Start Visual Studio 10 (Win32) Command Prompt
3. Verify that cl command works
4. Generate with cmake -G "Visual Studio 10" ...
