Drop hard-coded paths from this test. If we later need machine-specific
environment entries we can add dedicated infrastructure for it to be
configured locally.
Since `cmake --help` output now uses `[arch]` placeholders for the VS
generators, this test has been extracting invalid generator names.
Switch to using `cmake -E capabilities` to get a more robust listing of
the generators that does not depend on parsing human-readable help
output.
The `find_*` commands read search paths from both CMake variables
and from environment variables. Document how multiple values in
these variables should be separated.

Refactoring in commit 60307c5056 (cmGeneratorTarget: Replace source
classifier implementation, 2017-04-07) accidentally regressed support
for CMP0026's OLD behavior in the case of a source file written by
project code during the configure step after getting a LOCATION. We
should not perform full source classification until the generate step
because files written by the project's configure step may not exist yet.
Add special logic to support this case. Add a test case for it.

Add a `FILES_FROM_DIR` option to install a specific set of files
specified relative to a given directory and preserve their layout
in the destination. Currently we intend to use this internally
to implement other things so we don't provide an `install()`
porcelain or documentation yet.
Call sites such as those in the VS global generator that are used only
to reject per-config sources will now allow per-config object library
objects. The corresponding generators have already been taught to deal
with per-config object library files. Remaining call sites do not need
object library files anyway.
This will later allow `$<TARGET_OBJECTS:...>` generator expressions to
evaluate to values that vary by configuration (e.g. because each
configuration has its own object files).
Add internal infrastructure for looping over all sources for all
configurations and generating each source with exclusion marks
for configurations in which they do not participate. This does
not yet make per-config sources available in general but does
set up some of the needed infrastructure.
Unfortunately doing this cleanly will require major refactoring of both
the VS 7-9 generators and the VS 10+ generators (for separate reasons).
Instead add some extra internal structures to carry information where we
need it.
We can do this only with Xcode 5 and above where we list the object
library files in the per-config link line value. On older Xcode
versions we list the object files as sources so that dependencies work
correctly, but that does not allow per-config objects. (Xcode may allow
per-config source exclusion but only by base name.)
Multi-config generators like VS and Xcode need to loop over all the
source files first and then handle per-config information within
each one. Teach cmGeneratorTarget to provide such a view.
