- CD: it will build all assets and create a draft

+          The binaries here are compiled with Microsoft Visual C++. The following configurations are built:
+
+          Debug\ - no optimizations, using the static debug C runtime (/MTd)
+          Release\ - optimizations on, using the static C runtime (/MT)
+          ReleaseDLL\ - the library is compiled in a .dll (libcpuid.dll), which you'd need to ship alongside your executable. Static C runtime.
