make the C++11 compiler settings a bit more generic

C++0x is also detected
Fixed SimpleTable example

TableFixture.query() does not have const qualifiers on arguments,
so I removed it in descendant.
Cmake: There is no pthread in Windows
Cmake: Do not symlink under Windows (Causes error during build)

Error follows:

C:\Program Files
(x86)\MSBuild\Microsoft.Cpp\v4.0\V110\Microsoft.CppCommon.targets(172,5):
error MSB6006: "cmd.exe" exited with code 1.

It is annoying and totally undescriptive.
Maybe copying test assets would be fine?
