Since commit v3.1.0-rc1~227^2~1 (De-duplicate shared library targets in
generated link lines, 2014-07-30) we de-duplicate shared library targets
on the link line. However, some toolchains will fail linking if an
executable is linking to a shared library that is not used directly and
a static library that depends on the shared one. The linker may not
keep the reference to the shared library the first time and then the
symbols needed by the static library may not be found.
Fix this by reversing the direction of the for loop that removes the
duplicate shared libraries, in order to ensure that the last occurrence
of the library is left instead of the first one.
Extend Tests/Dependency with a case covering this behavior. Create an
executable that links to a shared library and a static library but only
needs the shared library as a dependency of the static library.

The change in commit v3.1.0-rc1~85^2 (ExternalProject: Fix download
retry logic, 2014-09-13) dropped the file(DOWNLOAD) EXPECTED_HASH
argument. This prevents file(DOWNLOAD) from skipping the download if
the output file already exists with the proper hash. Restore this check
with explicit code in the download script.

The PA-RISC architecture requires special options for GCC to prevent
linker errors when libraries reach a certain size and / or complexity.

documentation on -mlong-calls.
Since commit v3.1.0-rc1~1^2~1 (Xcode: Fix compiler id detection for iOS
tools, 2014-10-22) our compiler id detection project sets the product
type to 'com.apple.product-type.bundle.unit-test'. This causes the Ld
command line on which we match the path to the compiler to have a
'CompilerIdC.xctest/' component. The commit updated our regex to match
this, but placed it before the extra './' component that Xcode 5.0 and
below produce. Xcode <= 5.0 prints '/./CompilerIdC.xctest/', so switch
the order of the two components in the regex to match it.
The changes made by commit v3.1.0-rc1~46^2~1 (FindITK: Drop this ancient
compatibility module, 2014-10-02) and commit v3.1.0-rc1~46^2 (FindVTK:
Drop this ancient compatibility module, 2014-10-02) need to come with
release notes explaining that the modules were dropped. Also remove a
release not related to an update made to FindVTK that was never
released.
The value must be either a full path or relative to the configuration
directory, not relative to the 'static' directory. Use a full path.
This avoids a warning:
WARNING: favicon file 'cmake-favicon.ico' does not exist
It worked before because all 'static' directory content is copied to the
'_static' directory of html output anyway.
The logic introduced in commit v3.1.0-rc1~688^2~9 (Genex: Evaluate
TARGET_OBJECTS as a normal expression, 2014-02-26) ordered a map
by pointer value and then constructed a list of object files by
iterating over the map. This is not deterministic.
Since commit v3.1.0-rc1~688^2~5 (cmTarget: Allow any generator
expression in SOURCES property, 2014-03-18) the order produced by the
above-mentioned logic started being used for the actual list of object
files on the link line. Since it is not deterministic, spurious
re-links occur after re-running CMake simply because the order of
objects changed on the link line.
Fix this by iterating over the original vector of source files instead
of the map. This has a deterministic order.
Cleanup of Windows-wcl386.cmake in commit v3.1.0-rc1~693^2 (Watcom:
Cleanup Windows-wcl386 configuration, 2014-04-01) also introduced use of
the 'symfile' link option but did not mention it in the commit message.
There is no way to set the symbol file name of a target, so it is better
to revert that change. It is easy to run 'wstrip *' if the symbols need
to be stripped, but it is very difficult to get the right names for the
.sym files to install with debug/rel_with_deb_info configurations.
When we explain in add_definitions documentation that it is intended
only for preprocessor definitions, link to add_compile_options for
adding other flags. Also explicitly mention that the order of
add_definitions calls with respect to target creation does not matter.
This differs from the behavior now explicitly stated in the
documentation of add_compile_options.
Explain that it affects only targets added after the call. Fix the link
to the COMPILE_OPTIONS directory propert documentation. Update the
latter to explain that it is used to initialize the corresponding target
property when a target is created.

This reverts commit 5abfde6cb8.
The behaviors associated with implicit pulldown on variable lookup
seriously conflict with the optimizations made in these commits.
Basically, since values were copied upon variable lookup, not just on
PARENT_SCOPE, coupled with PARENT_SCOPE's behavior based on whether the
variable is in the current scope or not causes serious problems with not
storing a value for every variable at every scope.
The commit changed behavior of the following example, among other cases:
function(test_set)
set(blah "value2")
message("before PARENT_SCOPE blah=${blah}")
set(blah ${blah} PARENT_SCOPE)
message("after PARENT_SCOPE blah=${blah}")
endfunction()
set(blah value1)
test_set()
message("in parent scope, blah=${blah}")

Update the wording of some examples to avoid long lines in code blocks.
Otherwise the formatted documentation can exceed certain column width
limitations.
