In buggy code like
add_custom_command(
OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/out.h
MAIN_DEPENDENCY ${CMAKE_CURRENT_SOURCE_DIR}/out.h.in
...)
add_custom_command(
OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/out.h
...)
that has more than one rule to generate the same output CMake has always
used the first rule. However, since commit 2268c41a (Optimize custom
command full-path dependency lookup, 2013-08-06) we update the map from
output to cmSourceFile for every rule generating an output, effectively
keeping the last command instead of the first.
Fix this regression by checking for each map update if the output
already has an entry. If so, keep only the original entry. The VS 8
generator triggers this with a special case for generate.stamp rules
that differ between ZERO_CHECK and normal targets, so do not warn for
now. Leave a TODO comment for warning in the future.
In the common case of custom command dependencies specified via full
path optimize the implementation of GetSourceFileWithOutput using a
(hash) map. This is significantly faster than the existing linear
search. In the non-full-path case fall back to the existing linear
suffix search.
bf5a5bc bootstrap: Do not suppress CMAKE_OSX_SYSROOT if CFLAGS have -isysroot (#14324)
95f78e0 OS X: Search for SDK based on deployment target (#14324)
Revert commit a1c032b9 (bootstrap: Suppress CMAKE_OSX_SYSROOT if CFLAGS
have -isysroot, 2012-09-21). If MACOSX_DEPLOYMENT_TARGET is set then
CMAKE_OSX_DEPLOYMENT_TARGET will be set and Darwin.cmake will complain
if no CMAKE_OSX_SYSROOT is set. Just allow both -isysroot flags to
appear. The one generated by CMAKE_OSX_SYSROOT appears after and
overrides the one from CFLAGS/CXXFLAGS.
When available, use CMAKE_OSX_DEPLOYMENT_TARGET instead of the host OS X
version to select the default SDK. This makes sense because one should
use the SDK matching the deployment target.

* The ALIAS name must match a validity regex.
* Executables and libraries may be aliased.
* An ALIAS acts immutable. It can not be used as the lhs
of target_link_libraries or other commands.
* An ALIAS can be used with add_custom_command, add_custom_target,
and add_test in the same way regular targets can.
* The target of an ALIAS can be retrieved with the ALIASED_TARGET
target property.
* An ALIAS does not appear in the generated buildsystem. It
is kept separate from cmMakefile::Targets for that reason.
* A target may have multiple aliases.
* An ALIAS target may not itself have an alias.
* An IMPORTED target may not have an alias.
* An ALIAS may not be exported or imported.
Fix generation of the AdditionalIncludeDirectories element content to
escape for XML syntax. We already escape content of other elements,
this one was simply missing by accident.
Use the WIN32_EXECUTABLE target property only to set the SubSystem build
attribute default. When user-specified flags are later parsed they may
then override it.

It's acknowledged that check state should not generally nest,
so it should be cleared when used, for example, in Find* module.
Also, add optional RESET argument to cmake_push_check_state().
Add CMAKE_MODULE_LINKER_FLAGS_*, CMAKE_SHARED_LINKER_FLAGS_* and
CMAKE_STATIC_LINKER_FLAGS_* to cmDocumentVariables.cxx with a
similar documentation as CMAKE_EXE_LINKER_FLAGS_*.
Avoid requiring CMake 2.8.6 for CMakePushCheckState or CMake 2.8.8 for
CMakeExpandImportedTargets. Drop the custom versions of CMake modules
CheckCSource(Compiles|Runs) because we do not use the SAFESEH option
anyway.
Follow up change from commit ffa6faa4 (libarchive: Include cm_zlib.h to
get zlib used by CMake, 2011-12-20) for new includes of zlib.h in
updated libarchive.
