Teach the `install` and `export` commands to support installing and
exporting `OBJECT` libraries without their object files. Transform
them to `INTERFACE` libraries in such cases.
For `install(TARGETS)`, activate this when no destination for the object
files is specified. For `export`, activate this only under Xcode with
multiple architectures when we have no well-defined object file
locations to give to clients.
Our `cmake -E __create_def` helper used for `WINDOWS_EXPORT_ALL_SYMBOLS`
and merging of multiple `.def` files is available only with CMake hosted
on Windows. However, we may generate use of it on other platforms since
commit v3.9.0-rc1~405^2 (Support WINDOWS_EXPORT_ALL_SYMBOLS with `.def`
files, 2017-03-13) when multiple `.def` files are listed. This results
in a build error because the tool doesn't exist.
Fix our logic to avoid using the tool on non-Windows platforms. Instead
silently ignore all but the first `.def` source as we did before.
Issue: #17773
When using ccache with clang-tidy, ccache needs to wrap compiler
invocation, rather than cmake invocation. But it needs to do it without
affecting the command line that iwyu-like tools are receiving.
With this fix, if __run_co_compile is used, compile launcher is passed
using the new --launcher option, but if __run_co_compile is not needed,
compiler launcher is prepended to the command line as before.
To better illustrate the change: with this fix if running clang-tidy
with CXX_COMPILER_LAUNCHER set to "/usr/bin/time;-p;ccache" (time -p
added strictly for illustration purposes), the command line changes
from:
/usr/bin/time -p ccache cmake -E __run_co_compile \
--tidy=clang-tidy ... -- g++ ...
to:
cmake -E __run_co_compile \
--launcher="/usr/bin/time;-p;ccache" \
--tidy=clang-tidy ... -- g++ ...
This allows the compiler to be run via the launcher, but leaves tidy
(& friends) invocations unaffected.

All discovered executables were placed in a component, except for 'jar'.
This forced the use of find_package(Java) without any component
specification. This commit adds 'jar' to the 'Development' component,
because that's what it's used for.
Refactoring in commit v3.11.0-rc1~293^2~4 (Modules: Remove paths set as
global Unix prefixes, 2017-11-20) removed `PATH_SUFFIXES` options that
appeared to be used to cover subdirectories of the `PATHS` options that
were also removed. However, the path suffixes also apply to other
search paths and so should not be removed. Restore them.
Fixes: #17760
The test was expecting timestamps on day 1 in 1970 to start at 86400 but
they actually started at 0. This worked without `SOURCE_DATE_EPOCH=1`
because after 1972, leap days compensated the offset.
Fixes: #17762
Use a `git://` protocol URL documented by the repository hosting
infrastructure. After some updates to that infrastructure, the
`https://` URL with the `.git` extension no longer works reliably.
Use std::string (with correct initial size) in cmOutputConverter::Shell__GetArgument
instead of ostringstream. This avoids several re-allocations of the
string buffer. In addition, convert some of the private static members into
inline free functions to avoid function calls.
Store "Known" files separately in KnownFileSearchIndex. This avoids
creating the rather expensive cmSourceFileLocation object for source
files that are already known. For large projects this results in a
factor 3-4 speedup of cmGlobalGenerator::Compute().
When specifying a pure C# target in the `target_link_libraries()` call to
another C++ target, a `<ProjectReference>` was setup for it (we wanted this)
but also a corresponding `.lib` was added under `<AdditionalDependencies>`
(we didn't want this).
This change introduces a check that prevents `.lib` linker options from
being used when the corresponding target for that library is a C# target.
