Windows CMake File doesn't compile all examples / tests

[nathan lachenmyer]

I followed your instructions for building the GRT static libs in Visual Studio, but I get several errors while compiling (even the 32-bit version out of the box):

All of the errors seem derived from an issue with compiling Random::Random():

Some examples are still able to build (most of the classifier examples, for example) while most of the unit tests fail to build.

This also produces a static lib that I can link against, but almost any program I write and link has runtime exceptions. For example, any classifier that I instantiate:

	DecisionTree dTree;
        AdaBoost aBoost;

causes a memory access violation exception:

Exception thrown at 0x00007FF91447F8A5 (grt.dll) in exampleClassification.exe: 0xC0000005: Access violation writing location 0x00000000001506CC.

I've tried both the master and dev branches of the GRT, and they both seem to have these errors.

same issue here

I've figured out a short-term fix -- just include the entire GRT as source in Visual Studio and it'll compile. This means that you're not using the static lib, but at least you can compile and use it for now.
