INTERFACE libraries were created with the intention of collecting usage
requirements for use by other targets via `target_link_libraries`.
Therefore they were not allowed to have SOURCES and were not included in
the generated buildsystem. In practice, this has become limiting:
* Header-only libraries do have sources, they just do not compile.
Developers should be able to edit those sources (the header files)
in their IDE.
* Header-only libraries may need to generate some of their header
files via custom commands.
Some projects work around these limitations by pairing each interface
library with an `add_custom_target` that makes the header files and
custom commands appear in the generated buildsystem and in IDEs.
Lift such limitations by allowing INTERFACE libraries to have SOURCES.
For those with sources, add a corresponding build target to the
generated buildsystem.

If `Fortran_PREPROCESS` is explicitly turned off for a source file then
we know it does not need to be preprocessed. Teach the Ninja generator
to skip preprocessing in this case. Otherwise we still must preprocess
just in case.
Fixes: #18870
Since commit f6f4eb0907 (clang-tidy: Add driver mode argument,
2020-01-19) the `clang-tidy` tool rejects the new option:
Unknown command line argument '--driver-mode=g++'.
This is because we are adding the flag before the main compiler
command-line. Encode it with `--extra-arg-before=` so that `clang-tidy`
knows it is supposed to be part of the compiler command.

`clang-tidy` does not infer driver mode if it is not provided with a
JSON compilation database. This is exactly the way cmake launches it.
Hence clang-tidy will only use the default driver mode. Add an explicit
driver mode argument to avoid this.
Add a `JOB_POOL_PRECOMPILE_HEADER` target property to specify the pool
name, and its associated `CMAKE_JOB_POOL_PRECOMPILE_HEADER` variable.
Fixes: #20217
cmGeneratorExpression::Evaluate is a shortcut when only the evaluated string is
needed or an instance of cmCompiledGeneratorExpression cannot be cached.
Fixes: #19686
The quiet flag is false for all but one call to Evaluate. Make the quiet flag
a setter of cmCompiledGeneratorExpression to be able to remove it from the
Evaluate function signature.
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
The Intel Fortran compiler supports an extension that allows conditional
compilation based on preprocessor definitions specified on the command
line even when not preprocessing.
Fixes: #19664
