Specifying path in makefile (GNU make on Windows)

I'm using GNU make to build a project using Microsoft Visual C++, and I'd like to be able to run it from any CMD window rather than having to open the preconfigured one where the path (and various other environment variables) are preconfigured by a batch file. Ideally I'd like to define the relevant environment variables in the makefile itself, so all I need to do is pop open a CMD window and type "make".

By and large this is straightforward, but I'm struggling with PATH; so far every syntax I've tried for taking the standard PATH variable (as defined in the operating system) and appending the paths to the various build tools has failed.

Rather than go through the six or seven different syntaxes I have tried - some of which gave error messages, some of which didn't give error messages but just didn't work - I'll ask the question plainly:

So far the nearest I've come to success has been to define:

LINK = "C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\link.exe"

...and replace all subsequent references to "link.exe" by $(LINK), but this fails because link.exe has various dependencies (such as mspdb80.dll) that also have to be on the path.

This works:

DevEnvDir=C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE
VCINSTALLDIR=C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin

export Path:=$(DevEnvDir);$(VCINSTALLDIR);$(Path)

It was the need for "export" and for case-sensitivity that had defeated me before.
