I'm trying to link a number of libraries that are all built using the Platform toolset V100, but the main routine is compiled and linked with composer XE2013 with VS2012. (but the idea is to support all versions of the compiler and VS). But with one of the libraries I get the LNK2038 mismatch detected for _MSC_VER 1700. Is there a way in a command line to specify the platform toolset? I get messages when I've tried to add /p:PlatformToolset=v100 that it isn't recognized. Seems to be okay if I use a project in VS, but I need to use the command line as well.
