[CMake] EXCLUDE_FROM_ALL not working?

[Petr Kmoch]

Hi all.

I believe the reason is that EXCLUDE_FROM_ALL excludes the target from the
default 'all' target (Makefiles), which is represented by the custom target
ALL_BUILD in Visual Studio. EXCLUDE_FROM_DEFAULT_BUILD instead works with
Visual Studio's "Build Solution" command, which has no direct equivalent in
the Makefile world.

This means projects using VS solutions as "just a way to do command-line
builds on Windows" probably use ALL_BUILD and are fine with setting just
EXCLUDE_FROM_ALL. Projects which expect their developers to actively work
in the VS IDE (and thus use "Build Solution" and the like) have to set both
EXCLUDE_FROM_* properties.
