The Intel 16 format starts with the 0x0A 0x00 sequence that we use to
skip past the timestamp. This occurrence appears to be a version
number. Skip the first byte to avoid matching the sequence early.
Ideally we should gain a better understanding of the format and avoid
depending on short sequences that are likely to appear early by
coincidence, but this approach will suffice for now.

They regress existing builds that depend on the paths/symbols generated
previously. Another approach will be needed to solve the name collision
problem they were intended to solve. Leave the error diagnostics for
the colliding cases that were added in the same topic as the above
commits because they provide a useful early failure in relevant cases.
Fixes#16209.
Since commit v3.6.0-rc1~339^2 (CPack: Fix CPACK_INSTALL_CMAKE_PROJECTS
SubDirectory (4th) option, 2016-02-18) we now honor the "Directory"
option of this variable. Prior to that commit the value was not used
so projects may have used a placeholder value like `.` instead of `/`.
Treat `.` the same as `/` to restore compatibility with such projects.
Fixes#16205.
Commit v3.6.0-rc1~174^2~1 (cmGlobalNinjaGenerator: Clarify logic for
forcing use of response files, 2016-04-06) started using negative
command line length values to represent forced use of response files but
forgot to update `calculateCommandLineLengthLimit()` accordingly. Teach
it to return `0` instead of `-1` when no limit is computed from the
system to avoid forcing response files.

The fix in commit commit v3.6.0-rc1~82^2 (Drop find_(library|file|path)
prefixes from PATH on non-Windows, 2016-05-09) aggressively dropped
search of the entries in PATH itself in addition to the prefixes derived
from it. This regresses find modules that (incorrectly) depended on the
behavior, including some of our own modules such as FindImageMagick.
Restore the search of entries in PATH itself. If we want to drop it
later we will need to do so with a policy. Fixes#16192.
Revert commit v3.6.0-rc1~160^2 (try_compile: Honor
CMAKE_<LANG>_FLAGS_<CONFIG> changes, 2016-04-11). The behavior it
introduced can break projects that depend on the lack of such behavior.
We will have to introduce a policy or other mechanism to enable the
behavior in a compatible way. Simply revert it for now.
See issue #16174.
In commit v3.6.0-rc1~174^2 (Ninja: Honor CMAKE_NINJA_FORCE_RESPONSE_FILE
for compile rules, 2016-04-06), Ninja learned to look for
`CMAKE_NINJA_FORCE_RESPONSE_FILE` in the current scope or the
environment in order to force response file usage for all compilation
rules.
However, on Windows, the RC compiler goes through cmcldeps which does a
`replace(output, output + ".dep.obj")` on the command line. However,
with a response file (which we name `output + ".rsp"`), the response
file path is replaced instead causing the compiler to (correctly)
complain that the response file `output + ".dep.obj.rsp"` does not
exist.
What needs to happen is for cmcldeps to look through the response file,
replace *its* contents and place it in the `output + ".dep.obj.rsp"`
file.
Also add a test which actually compiles an RC file into a library and
executable for all generators on Windows and additionally test
`CMAKE_NINJA_FORCE_RESPONSE_FILE` for Ninja generators.
Fixes#16167.
In commit v3.6.0-rc1~279^2~10 (VS: in Clang/C2 toolset, setup correct
compiler settings, 2016-02-18) a flag mapping was added for the clang
`-Os` flag. However, this collides with a mapping we already had for
the MSVC flag of the same name. This is a symptom of a larger problem
in that the VS generators need a per-toolset flag map (issue #16153).
For now, simply drop the new mapping and drop `-Os` from clang compiler
flags in the MinSizeRel configuration.

When we are on OSX and we are launching cmake-gui from a symlink, the
application will fail to launch as it can't find the qt.conf file which
tells it what the name of the plugin folder is. We need to add this path
BEFORE the application is constructed as that is what triggers the
searching for the platform plugins
Policy CMP0026 deprecated the LOCATION property, and we have long
provided a $<TARGET_FILE:...> generator expression. However, if
a project tries to use $<TARGET_PROPERTY:...,LOCATION> we should
at least not crash.
The compatibility implementation of the LOCATION property uses
cmGlobalGenerator::CreateGenerationObjects to create the structures
needed to evaluate the property before generation starts. The
implementation assumed that accessing the property could only be done
during configuration (via the typical get_property command use case).
The $<TARGET_PROPERTY:...,LOCATION> genex causes the LOCATION property
to be accessed during generation. Calling CreateGenerationObjects
during generation blows away all the objects currently being used for
generation and is not safe. Add a condition to call it only when
configuration is not finished.
Use clang-tidy's performance-unnecessary-copy-initialization checker.
After applying the fix-its (which turns the copies into const&), revise
the changes and see whether the copies can be removed entirely by using
the original instead.
Use clang-tidy's performance-unnecessary-value-param checker to find
value parameter declarations of expensive to copy types that are not
modified inside the function. Ignore findings in kwsys.
After applying the fix-its, manually change `const T&` to `T const&`.
d256ba07 try_compile: Optionally forward custom platform variables to test project
fb4791b3 cmCoreTryCompile: Refactor forwarding of variables to test project
Add a `CMAKE_TRY_COMPILE_PLATFORM_VARIABLES` variable to specify a list
of custom variables to be forwarded to a `try_compile` test project.
This will be useful for platform information modules or toolchain files
to forward some platform-specific set of variables from the host project
(perhaps set in its cache) to the test project so that it can build the
same way.
De-duplicate the logic that constructs the cmake `-D` flag used to pass
variables into the test project cache. Also subsume variables that were
propagated by generating `set()` commands in the project and pass them
as cache entries instead.
