Historically CMake has always expanded ${} variable references in the
values given to include_directories(), link_directories(), and
link_libraries(). This has been unnecessary since general ${}
evaluation syntax was added to the language a LONG time ago, but has
remained for compatibility with VERY early CMake versions.
For a long time the re-expansion was a lightweight operation because it
was only processed once at the directory level and the fast-path of
cmMakefile::ExpandVariablesInString was usually taken because values did
not have any '$' in them. Then commit d899eb71 (Call
ExpandVariablesInString for each target's INCLUDE_DIRECTORIES,
2012-02-22) made the operation a bit heavier because the expansion is
now needed on a per-target basis. In the future we will support
generator expressions in INCLUDE_DIRECTORIES with $<> syntax, so the
fast-path in cmMakefile::ExpandVariablesInString will no longer be taken
and re-expansion will be very expensive.
Add policy CMP0019 to skip the re-expansion altogether in NEW behavior.
In OLD behavior perform the expansion but improve the fast-path
heuristic to match ${} but not $<>. If the policy is not set then warn
if expansion actually does anything. We expect this to be encountered
very rarely in practice.
CONFIGURE_PACKAGE_CONFIG_FILE() now additionally generates
"Any changes to this file will be overwritten by the next CMake run
The input file was FooConfig.cmake.in"
into the configured file.

Eliminate the platform difference in calling stat. We call stat normally
in other places in the CMake code base just fine. Works everywhere we
work. Will hopefully also fix the Borland Continuous dashboard failure
that is occurring with respect to correctly measuring the modification
time of a freshly generated file.
Handle OpenBSD specific paths in Qt3/Qt4, allowing concurrent building
and installation. Some common programs are renamed with suffixes of
either 3 or 4. Also, allow qt3/qt4 installed under /usr/local to be
searched and recognized appropriately.

Use "size_t" instead of "std::size_t" so that it compiles with
Visual Studio 6, too.
Fix warnings about shadowed "tmp" local variable and ordering of
member variables vs. lines of code in the constructor initializer
list.
Solution folders are supported as read-only in the VS11 Express
Edition, so do not prohibit their use just because we detect the
express edition (as we did in the VS10 generator).

Use same technique here with UuidToString as already found in
cmGlobalVisualStudio7Generator::CreateGUID to avoid using a type
that is not defined on older systems... (VS 7.0 and Borland)

caught by clang's -fsanitize=shift. A small unsigned int was
promoted, according to C's regular promotion rules, to a signed
int, it was then left shifted. This sometimes pushed a 1 into
the sign bit, which is undefined behaviour. Fixed by using
unsigned temporaries.
Previously it was necessary for writers of Config files
which incude exported target files to write the guard themselves, but
this was not immediately obvious or documented. Options for them
would be to use a variable, or an INHERITED directory property in an
effort to avoid accidental name clashes in all contexts in
which find_package can be used.
Getting this right requires boiler plate code, so generate a simpler
check automatically instead.
