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.
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

Use `target_link_libraries` to set `INTERFACE_LINK_LIBRARIES` so that
the `debug` and `optimized` keywords work.
In commit a8e0a6b3e4 (FindHDF5: Port changes from VTK, 2020-06-10,
v3.19.0-rc1~312^2~1) we added use of `HDF5_LIBRARIES`, but the value may
contain `debug` and `optimized` keywords.
Fixes: #21637
The change in commit 901386f646 (cmake-mode.el: Add navigation by
function and macro, 2020-12-11) introduced a regression. Emacs 26 could
not load cmake-mode.el anymore. Use `(not-char ")")`, not `(not ")")`.
