Before running vcvarsall.bat it doesn't.
After running vcvarsall.bat it does.

There are no errors when running cmake in a clean build tree after
running vcvarsall.bat.
Problems are only in this scenario;

1. Open command prompt.
2. Run cmake. (error "To use the NMake generator, cmake must be run from

3. Run vcvarsall.bat
4. Run cmake again. (error
"CMakeFiles\cmTryCompileExec.dir\testCCompiler.c.obj : fatal error
LNK1112: module machine type 'X86' conflicts with target machine type
'x64'")
