Summary0010473: Default generator on Windows
DescriptionIt would be handy for CMake not to default to the highest MSVC installed when run on Windows. Better would be:
a) check CMAKE_GENERATOR environment variable for which one to use. This should be quite easy and can still default to the newest MSVC version, but this should be checked first.
b) find available compilers at runtime (ie when running CMake) and let the user select the one he wants from a list. This would be a performance hit and not preferred

This would allow those few people using either more than one compiler or mingw(-w64/w32) to just run "cmake .." and (g/mingw32-)make without the need for -G"MinGW Makefiles". It shouldn't be too hard to implement and would simplify working with CMake a lot.

The attached patch modifies cmake::ActualConfigure so that when configuring a new project it will check the environment variable CMAKE_DEFAULT_GENERATOR before trying platform-specific generators.

I realize there are more pressing concerns, but is it possible to get some kind of an acknowledgement even if the patch as-is can't be merged yet?

It should use the getenv wrapper in cmSystemTools:
  static const char* GetEnv(const char* key);


cmSystemTools::GetEnv("CMAKE_DEFAULT_GENERATOR")

Thanks for your response. I didn't mean to sound impatient, it's just that this is a feature I'd been interested in myself, and it seemed like a simple fix. :)

I've attached a patch which uses the new name, and cleaned up the code a bit.

Has there been any further consideration on this?
