This is a follow-up to commit b696f78073 (cmDepends: merge dependers of
depend makefile, 2020-12-18). NMake of visual studio has many versions
that not support long line dependencies of make rule.

Fixes: #21681
The Xcode "new build system" only considers a script build phase up to
date if it has run before, even if outputs are newer than inputs. Use a
deterministic object id for script build phases associated with custom
commands so that they do not need to re-run after CMake re-generates the
project.
Fixes: #21669
Extend Qt(4|5)Autogen.RerunMocBasic to check the following situation:
Class MyObject3 is a QObject-derived class without Q_OBJECT macro.
It's declared in myobject3.h that is not included by any file that is
input of AutoMoc (this is why we had to add PlainObject).
If myobject3.h were included by main.cpp, then AutoMoc would already
track this dependency, because main.cpp has a Q_OBJECT macro.
After the initial build(s), the Q_OBJECT macro is added to myobject3.h,
and an incremental build is run. With Qt >= 5.15 and Ninja, the build
fails, because AutoMoc is not run due to the missing dependency to
myobject3.h.
Test that removing / adding a Q_OBJECT macro doesn't break incremental
builds.
This was initially done to test the fix for #21620, but the test passes
without the fix. The reason is that test1.h is included by main.cpp, which
contains a Q_OBJECT macro, meaning that test1.h is in AutoMoc's
dependencies transitively.
In a subsequent patch we want to extend RerunMocBasic to test the
removal and addition of Q_OBJECT macros works when building
incrementally.
For that, properly generated dependencies are necessary. Currently, the
MocBasic test project is configured using try_compile, and that turns
off the generation of depfiles.
Replace the try_compile call with execute_command calls that first
configure and then build the test project.
The new target property `EXPORT_COMPILE_COMMANDS` associated with the
existing global variable can be used to optionally configure targets for
their compile commands to be exported.
Fixes: #19462
Since one depender has multiple dependees, depend makefile generated
same depender line by line, to reduce file size and refine make file
parse speed, merge same dependers to one. And add a testcase for
large depend.make which generated source file includes 20000 header
files and run build and incremental build

Since 3.19, CMake generates a deprecation warning when using a minimum
version less than 2.8.12. This eliminates those warnings generated
during tests, which are typically hidden from the user and developer but
are being generated nonetheless.
Generalize the change from commit bffb17be3d (Xcode: Inherit target
library and framework search paths from project, 2020-11-04,
v3.19.0-rc3~4^2) to apply to framework and other kinds of search paths
added either for include directories or for linking.
Issue: #21617
