1040e690 cmSystemTools: Teach RunSingleCommand to merge child pipes when possible
ce3b713b cmSystemTools: Simplify RunSingleCommand output string construction
dc039cc0 cmSystemTools: Drop redundant condition in RunSingleCommand
ffa2a8c9 cmSystemTools: Rename OUTPUT_NORMAL to OUTPUT_FORWARD to clarify its purpose
92e9bb21 cmcmd.cxx: Remove unused code in __run_iwyu implementation
fb1526f5 cmake: Change `-E chdir` to pass through stdout/stderr directly
Audit the code to make sure there are no callers that use OUTPUT_MERGE
with separate capture strings. Then change RunSingleCommand to
implement output merging by giving the child process a single pipe for
both its stdout and stderr descriptors. This will more cleanly merge
the content on atomic write boundaries in the child instead of on
arbitrary buffering boundaries in the parent.
The OUTPUT_NORMAL value is not really "normal" and has only one caller.
Rename it to OUTPUT_FORWARD to clarify that we are explicitly forwarding
the output.
aea1b036 Fix export of STATIC library PRIVATE dependencies with CMP0022 NEW
e5cbec14 Tests: Use CMP0022 NEW behavior in some ExportImport cases
0ca122fc Tests: Isolate policy changes in ExportImport test
The original value is saved in `_pkg_config_path_old`. Fix this typo
left by commit v3.1.0-rc1~763^2 (FindPkgConfig: Extend PKG_CONFIG_PATH
using CMake variables, 2014-03-06).
Some compilers may add their own RPATH entries when invoking the linker.
For example, a GCC installation may contain the following definition in
the specs file:
*link_libgcc:
%D -rpath <<some specific rpath in which libstdc++.so can be found>>
In this case binaries may contain RPATH entries that CMake did not add.
When we update the RPATH on installation we must preserve these entries
even if CMake thinks the INSTALL_RPATH value should be empty.
Fix this by always using file(RPATH_CHANGE) and teach it to behave as
file(RPATH_REMOVE) if the actual RPATH in the file is empty after
replacing the build-tree RPATH with the install-tree RPATH. This will
preserve any compiler-added RPATH value instead of removing it.
In Modules/Platform/WindowsPaths.cmake our previously recorded
environment variable combinations no longer seem to be correct. For
example, a 64-bit cmake binary may see ProgramW6432 in the environment
and end up not considering the "ProgramFiles(x86)" variable. Instead
check for all possible environment variables in the preferred order and
then remove duplicates.

The target_link_libraries command records the PRIVATE dependencies of a
STATIC library in INTERFACE_LINK_LIBRARIES as "$<LINK_ONLY:dep>". This
hides the target name from export namespacing logic inside a generator
expression. When user-written generator expressions reference a target
name they must put it inside a "$<TARGET_NAME:dep>" expression to allow
the export logic to rename the target. In the case that the private
dependency is not already a generator expression, target_link_libraries
must use "$<LINK_ONLY:$<TARGET_NAME:dep>>" to allow the export logic to
rename the target.

Add `VERBATIM` to all `add_custom_command` calls so that CMake will
escape arguments properly even when special characters such as "()" are
present.

Since commit v3.3.0-rc1~410^2~3 (ctest_test: Add QUIET option,
2015-02-17) if tests fail when QUIET is used one sees:
The following tests FAILED:
but not the subsequent line(s) indicating which tests failed.
Restore the list of failed tests.
