[CMake] nmake build with different options at command line

[David Cole]

You cannot do the same thing with nmake. You must do it with cmake.

If you want to build multiple configurations in the same build tree, you
must use the Visual Studio or Xcode generators. The nmake and other Makefile
generators only support ONE CMAKE_BUILD_TYPE in a given build tree.

The way to do it with nmake is to have two separate build trees. One for
Release and one for Debug. Then, in each of those directories, you may
simply run "nmake". Switch from one directory to the other to change
configurations with a make file generator.


HTH,
David
