I know there have been a few posts on the topic but didn't get a satisfying answer:
I develop C++ code and use CMake as a build system. I usually work in a Linux environment. Now I want to port my code to windows, and be able to edit and compile it within emacs.
I generate "NMAKE Makefiles" with CMake. This works fine but only if I run nmake from "Visual Studio Command Line". Visual Studio Command Line is like the regular Windows command line, with a bunch of environment variable set up. If I run nmake from the regular windows command line, I end up with "nmake: unrecognized command" (not exactly the error message this is an approximate translation from french).
Following the old documentation in emacs wiki I found the .bat file which sets up the variables. If I run the .bat from regular command line then call nmake, it works. But when I run name from emacs, it just run the program as in a plain, regular command line, which knows nothing about nmake and the environment variables.
How can I make everything works together then?
The best approach would be to write a bat file, which contains the necessary settings like this:
call "C:\Program Files\Microsoft Visual Studio 10.0\VC\bin\vcvars32.bat"
nmake
and then call this file from emacs instead of the plain "nmake" command. This redoes the initialization every time, but should be fast enough.
