Nils Gladitz 144cc6f1f9 Ninja: Add source location as include directory for preprocessed files
Fortran INCLUDE statements are not handled by the preprocessor.

Since the location of the preprocessed file is distinct from the
original source file explicitly add the source file's directory
as an include path in the actual compile step (not the preprocessing step)
so INCLUDE can find it.

Brad King cda8c782db cmGlobalGenerator: Optimize FindMakefile method with an index
This method is used by directory get/set APIs.  With the new
`SUBDIRECTORIES` and `BUILDSYSTEM_TARGETS` methods projects may now make
heavy use of these APIs to traverse their directory structure and
process targets.  Make this faster by indexing the directory lookups.

Brad King 39ebfc79e6 Ninja: Add explicit preprocessing step for Fortran
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.

Brad King 764775c4dd Fix XCODE_ATTRIBUTE_..._LOCATION target property lookup
Refactoring in commit v3.5.0-rc1~272^2~16 (cmGeneratorTarget: Add API for
property keys, 2015-10-25) changed the Xcode generator implementation of
`XCODE_ATTRIBUTE_...` properties to use the target `GetProperty` method on each
`XCODE_ATTRIBUTE_...` property listed by `GetPropertyKeys` instead of looping
over the property entries directly.  This made the lookup of property names of
the form `XCODE_ATTRIBUTE_..._LOCATION` accidentally trigger the computed
property logic for the undocumented/legacy `<CONFIG>_LOCATION` property.  Of
course the computed property value is not the same as the value stored in the
`XCODE_ATTRIBUTE_..._LOCATION` property.  Fix the computed property logic to
avoid triggering on `XCODE_ATTRIBUTE_...` attributes.

Brad King b5ac8b8aa7 Fortran: Add support for submodule syntax in dependency scanning
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.

Brad King 7b5f85677c Fortran: Use module dir flag if needed for default module directory
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.
