Previously we would warn when the local and cache version of a variable
exists, but this use case doesn't need a warning as it maintains backwards
compatibility.
Previously the command considered non-absolute source file paths relative to
the associated target on the LHS. This causes problems in incremental builds
where files are added from subdirectories and forces users to workaround by
manually converting to absolute paths. Change this to enable more intuitive
usage by projects.
Fixes#17981
find_program() incorrectly prepended search path components
to absolute file paths, and incorrectly searched the current
working directory for files that contained no directory
separators.
* Replace calls cmFindProgramHelper::CheckDirectory(std::string())
with call of new method cmFindProgramHelper::CheckCompoundNames()
that checks for the presence of a directory separator in the
file name.
* Use cmSystemTools::CollapseCombinedPath rather than string
concatenation to properly combine absolute file names with
search path components.
* Add unit tests to verify corrections.
Fixes: #18044
The change in commit v3.11.3~3^2 (cmSystemTools: Revert GetRealPath
implementation on Windows, 2018-05-29) broke the feature added by commit
v3.11.0-rc1~64^2 (Windows: Add support for running CMake tools through a
symlink, 2018-01-21). Use `GetRealPathResolvingWindowsSubst` in the
latter code path to restore it.

In commit a203fcc63d (cmake: Teach '-E tar' to report errors copying
data, 2018-05-16) we introduced use of `la_ssize_t` but that was not
available until libarchive 3.3.1. Switch to the `__LA_SSIZE_T` macro
we use elsewhere.
Run the `clang-format.bash` script to update all our C and C++ code to a
new style defined by `.clang-format`. Use `clang-format` version 6.0.
