For now, compiler extensions are no longer activated on CMake sources.
However these extensions are still used for various third parties.
This MR is a partial answer to the issue #20454.
For users of CMake who want to optimize their scripts if they take a
while to run, this commit adds the ability to output profiling data.
To enable this output, it adds the two command line parameters
to select the output path and format.
This commit adds the first profiling format of type ``google-trace``,
which is the output is a JSON file containing Duration events as per the
Google Trace Format specification:

Introduce the function cmReadGccDepfile that parses a GCC-style depfile
and returns its content. The implementation uses a lexer that is
modeled after the re2c implementation in Ninja.
The sample files of the autotest have been created with gcc 8.3.0.
This depfile reader is to be used by the Autogen facility to make use
of the depfiles that are generated by Qt's meta object compiler.
* Added a fairly comprehensive test suite
* Separated the graph traversal logic from the Graphviz generation
code by introducing a new class, cmLinkItemsGraphVisitor{.h,cxx}
* Made the graph traversal logic less ad-hoc by using existing
methods in the GlobalGenerator; this fixed a few bugs
* Added support for new target types: custom targets, object
and unknown libraries
* Improved support for ALIAS libraries by showing the alias(es)
in the graph
* Introduced new flags to control those new libraries (consistent
with existing flags)
* Updated the documentation
* Removed useless setting to set graph type in dot file
* Improved the node/edge shapes (nicer, more consistent)
* Added a legend to the graph
* Some refactoring and cleanup of the Graphviz generation code
* Added test and fix for issue 19746
This algorithm is used to determine whether or not a test can
execute with the available resources. It uses a recursive largest-
first algorithm to try to place the tests into their respective
slots.
Provide a standardized way to handle the C++ "standard" headers
customized to be used with current CMake C++ standard constraints.
Offer under directory `cm` headers which can be used as direct
replacements of the standard ones. For example:
#include <cm/string_view>
can be used safely for CMake development in place of the `<string_view>`
standard header.
Fixes: #19491
Remove -DCMAKE_BUILD_WITH_CMAKE from Source/CMakeLists.txt. Remove
CMAKE_BOOTSTRAP from bootstrap's cmConfigure.h. Add -DCMAKE_BOOTSTRAP
to all bootstrap sources, and remove the Unix specialization of
CMAKE_BOOTSTRAP in libuv (a review of the libuv code suggests that
this will not have an effect on the Windows build.)
