PTM DLL Static Build

On windows it is not straightforward to compile to a DLL by mixing /MT (static) and /MD (dynamic) linking flags. However we want to create exes (hydro, qual, gtm) that have no dependencies on system libraries at runtime. This means we compile all libraries with /MT flags.

DSM2-174 - PTM DLL compiling issue Resolved

PTM is a dll so we have to override the libraries the compiler and linker search for by default.

For the standard C/C++ libraries more information at https://docs.microsoft.com/en-us/cpp/c-runtime-library/crt-library-features?view=vs-2019

For the Intel libraries more information at https://software.intel.com/en-us/articles/libraries-provided-by-intelr-c-compiler-for-windows-and-intel-parallel-composer

The following libraries are then ignored so that the static versions of the libraries are packaged into the .dll file itself. This increases the size of the DLL but then during runtime there are no other dependencies on any system or intel libraries. In other words, it can stand alone and run.

The libraries ignored are 

msvcrt.lib;libmmd.lib; mscvcprt.lib;libucrtd.lib;

If you ever need to see all the libraries being used turn the /VERBOSE feature on the linker options in Visual Studio
