Since commit d74e651b78 (Makefiles: Re-implement makefile target path
escaping and quoting, 2020-04-10, v3.18.0-rc1~334^2~1), `WriteMakeRule`
now correctly escapes `$` in make target paths as `$$`. However, this
caused an existing call site to escape the `$(VERBOSE)` variable
reference in the `.SILENT` prefix, making it ineffective. Sub-makefiles
are invoked with `MAKESILENT`, so this bug matters only for the `all`
target, which emits progress messages from toplevel.
Before:
# Suppress display of executed commands.
$$(VERBOSE).SILENT:
After:
# Suppress display of executed commands.
$(VERBOSE).SILENT:
It was very easy to forgot to add all the possible language
properties that try_compile might need. Refactored the code
to make it harder to skip flags.
This changes adds the missing language properties for
the CUDA, Fortran, OBJC, OBJCXX, and Swift languages:
- CMAKE_<LANG>_COMPILER_EXTERNAL_TOOLCHAIN
- CMAKE_<LANG>_COMPILER_TARGET
- CMAKE_<LANG>_LINK_NO_PIE_SUPPORTED
- CMAKE_<LANG>_PIE_SUPPORTED
This support was actually added by removing a superfluous check that was
too eager in cmLinkItemGraphVisitor.cxx.
Extended the existing Graphviz tests to include this particular case,
and re-generated the expected output files.
Fixes: #20720
Prior to 147d36c, the build tool was found before the toolset was
selected, but was changed to be found after in order to support a
64-bit MSBuild (introduced in da402a0.) However, a bug was found in
64-bit MSBuild, which resulted in da402a0 being reverted in
f3cedf3 (but 147d36c was not reverted.) Move FindMakeProgram() even
earlier than it was before 147d36c, before CMakeDetermineSystem is
called, so that the Visual Studio Android support can report its
sysroot, giving Android-Determine the information it needs to
inspect the NDK.
When the bug in 64-bit MSBuild is fixed, we will have a chicken-and-
egg problem, but we don't need to worry about it for now.
Issue a deprecation warning on calls to `cmake_minimum_required` or
`cmake_policy` that set policies based on versions older than 2.8.12.
Note that the effective policy version includes `...<max>` treatment.
This is important in combination with commit ca24b70d31 (Export: Specify
a policy range in exported files, 2020-05-16, v3.18.0-rc1~133^2).

Try linking all target linked libraries through frameworks build phase
instead of linker flags, thus letting Xcode manage build product paths
correctly. Prevent adding duplicate entries to "Link Binary With
Libraries" build phase.
Add check for configuration-dependent linking - in case the library is
not present in all configurations revert back to linker flags which are
per-configuration.
This does change the order of libraries linked, but that does not seem
to matter for Apple linkers invoked by Xcode, even for static libraries.
The linker will go back and re-consider a static library from earlier
on the link line when more symbols from its objects are needed.
Fixes: #14185
cmCoreTryCompile had significant code duplication around handling
languages that offer standard levels. This refactoring reduces
the complexity and makes it easier to add new languages in the
future.
