All Fortran sources need to be preprocessed before any source may be
compiled so that module dependencies can be (later) extracted. Factor
out an explicit preprocessing step preceding compilation. Use Ninja
depfile dependencies on the preprocessing step and then compile the
already-preprocessed source with a separate build statement that depends
explicitly only on the preprocessor output. Later we will insert
dynamic discovery of module dependencies between these steps.
Create an internal `cmake -E cmake_ninja_dyndep` tool to read the "ddi"
files generated by `cmake -E cmake_ninja_depends` from all sources in a
target and generate a ninja dyndep file that tells Ninja about Fortran
module dependencies within the target and on target dependencies.
Create an internal `cmake -E cmake_ninja_depends` tool to scan an
already-preprocessed Fortran translation unit for modules that it
provides or requires. Save the information in a "ddi" file with a
CMake-private format for intermediate dynamic dependency information.
This file may the be loaded by another tool to be added later.
Kitware maintains a branch of Ninja with support for dynamically
discovered dependencies (dyndep) that has not yet been accepted
upstream. Add an internal API to check whether the Ninja version in use
for the build supports this feature.
Delay rejection of Fortran until after we've determined the version of
the `ninja` tool to be used. This will later allow us to enable Fortran
support based on the version of ninja.
While at it, make the rejection an immediate fatal error. Also provide
a stack trace so readers know what code tried to enable Fortran.
Use it to split pipe and stdin/out handling out of cmServer itself.
The server will shut down when it looses its connection to the client.
This has the nice property that a crashing client will cause the server
to terminate as the OS will close the connection on behave of the client.

Enable the server to support development with some helper tools:
You can now request debug information with statistics on how
long execution of a command took, how long it took to serialize
the JSON files, and how big the serialized JSON string is.
Also allow to dump results into a file.
Add new test properties:
* FIXTURES_SETUP
* FIXTURES_CLEANUP
* FIXTURES_REQUIRED
to specify the roles and dependencies of tests providing/using
test fixtures.
If a `ctest_*` command has CAPTURE_CMAKE_ERROR then any errors generated
by cmake during that command will cause the value to be assigned `-1`.
This will prevent a `ctest -S` script from returning non-zero unless the
script explicitly calls `message(FATAL_ERROR)`.
Fortran 2008 [1] adds support for a new syntax related to modules:
submodule ( ParentModule ) SubModule
submodule ( ParentModule : SubModule ) NestedSubModule
Both of these mean that the current source file requires the module
`ParentModule` to be available if it is not provided in the current
file. Teach our Fortran dependency scanner to parse this syntax to
extract this relationship. For now simply tolerate the nested submodule
case and extract only the dependency it expresses on the main module.
Further work will be needed to extract dependencies among nested
submodules.

Fortran allows the syntax
MODULE PROCEDURE ...
MODULE FUNCTION ...
MODULE SUBROUTINE ...
to declare procedures/functions/subroutines that are members of modules.
Do not treat such syntax as the definition of a module with one of these
names.

Ninja 1.7 introduced support for implicit outputs on build statements.
Add an internal API to check whether the Ninja version in use for the
build supports this feature.
Ninja 1.7 introduced support for implicit outputs on build statements.
Teach WriteBuild to generate the corresponding syntax. Leave it up to
callers to decide whether implicit outputs are supported by the Ninja
version in use. For now simply update all call sites to pass an empty
list of implicit outputs.
Our buildsystem model says that the default Fortran module output
directory is the build tree directory corresponding to the source tree
`CMakeLists.txt` file adding the current target. Extend
`cmGeneratorTarget::GetFortranModuleDirectory` to allow generators to
pass in the compiler working directory. If the working directory does
not match the default Fortran module output directory then we need an
explicit module directory flag (e.g. `-J`) to tell the compiler to
put/use modules in the latter.
This does not affect the Makefile generator but will be useful for
future introduction of Fortran support to the Ninja generator.

Allow for experimental cmProtocolVersions, which will only ever get
listed if the server was started with the (undocumented)
"--experimental" flag.
Mark current protocol version 1.0 as experimental.
