Brad King 4f3f75a246 FortranCInterface: Document mangling result variables publicly
Some projects may want to use the detailed mangling information
directly instead of using the FortranCInterface_HEADER function.
We already provide variables encoding the mangling information,
so just document them as available.

Brad King 47f24cbcca FortranCInterface: Improve documentation formatting and organization
Organize content into sections.  Define functions via explicit markup
blocks so we can cross-reference them.

Brad King 9d1f40ccc1 FortranCInterface: Convert docs to a bracket comment
Use a bracket comment to hold the documentation instead of a block of
line comments.  This will make further updates easier.

Brad King b3795df2f4 FortranCInterface: Do not use cmake_policy(VERSION)
Do not force a specific policy version in the module because it prevents
projects from setting newer policies to NEW.  In particular, projects
may want to set CMP0056 to NEW to affect any try_compile calls in this
module.

Use of this was added in commit v2.8.2~714 (FortranCInterface: Use CMake
2.8.0 behavior, 2009-11-17) in order to set CMP0007 to NEW.  Simply set
this policy explicitly instead.

Brad King 71491bbe8f FortranCInterface: Pass all flags to VERIFY project (#13579)
Teach FortranCInterface_VERIFY to build the test project in a specific
configuration and pass all flags for that configuration.  This ensures
that any modifications made by the user or project to the flag are used in
the test project consistently.

Kitware Robot 9db3116226 Remove CMake-language block-end command arguments
Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block.  This is no longer the preferred style.

Run the following shell code:

for c in else endif endforeach endfunction endmacro endwhile; do
    echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
egrep -z -v 'Tests/CMakeTests/While-Endwhile-' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed

Brad King 4cb73c43ac FortranCInterface: Work around mingw32-make trouble with parens
The mingw32-make tool does not handle parenthesis in the path to a
source file consistently.  When CMake is installed in a typical location
like "c:\Program Files (x86)\CMake 2.8\" the mingw32-make tool fails on
the FortranCInterface detection project sometimes with errors like

 >mingw32-make -f CMakeFiles\myfort.dir\build.make CMakeFiles/myfort.dir/my_module.f90.obj
 mingw32-make: *** No rule to make target `x86)/CMake 2.8/share/cmake-2.8/Modules/FortranCInterface/my_module.f90)',
 needed by `CMakeFiles/myfort.dir/my_module.f90.obj'.  Stop.

due to parens in the path to the FortranCInterface source directory.
However, the behavior varies with the file name of build.make:

 >copy CMakeFiles\myfort.dir\build.make CMakeFiles\myfort.dir\build2.make
 >mingw32-make -f CMakeFiles\myfort.dir\build2.make CMakeFiles/myfort.dir/my_module.f90.obj
 [  3%] Building Fortran object CMakeFiles/myfort.dir/my_module.f90.obj

Tested with

 >mingw32-make -v
 GNU Make 3.82
 Built for i386-pc-mingw32

Work around the problem by copying the whole FortranCInterface source
directory in to the project build tree.

Brad King 0306080e6e FortranCInterface: Support '=' in language flags
The commit "FortranCInterface: Honor language flags in checks" taught
the FortranCInterface module to pass C and Fortran flags into its
detection and verification checks.  We improve on the change to allow
the '=' character in the language flags.  This requires passing the
cache entry type with the -D options.

Brad King 1699836b06 FortranCInterface: Honor language flags in checks
We pass CMAKE_C_FLAGS, CMAKE_CXX_FLAGS, and CMAKE_Fortran_FLAGS through
try_compile() for the FortranCInterface Detect and Verify projects.
This honors user-specified compiler flags for each language, thus
supporting flags that affect the Fortran mangling.

Brad King 184a3418e6 FortranCInterface: Use CMake 2.8.0 behavior
The FortranCInterface module should execute with CMake 2.8.0 behavior
even if policies are set differently by the including project.  In
particular, it makes use of empty list elements and therefore expects
NEW behavior of CMP0007.

Brad King 3a666595c9 Convert CMake non-find modules to BSD License
This adds copyright/license notification blocks CMake's non-find
modules.  Most of the modules had no notices at all.  Some had notices
referring to the BSD license already.  This commit normalizes existing
notices and adds missing notices.

Brad King 78160cee6e Make FortranCInterface_VERIFY verbose on failure
We enable verbose build output in the try_compile of the simple project.
This makes valuable information available in the case of failure.

Brad King a9be85da2e Create FortranCInterface_VERIFY function
This function builds a simple test project using a combination of
Fortran and C (and optionally C++) to verify that the compilers are
compatible.  The idea is to help projects report very early to users
that the compilers specified cannot mix languages.

Brad King 14f7a043e3 Teach FortranCInterface to load outside results
We split the main detection logic into a Detect.cmake support module and
load it only when detection results are not already available.  This
allows results computed by the main project to be used in try-compile
projects without recomputing them.  The call to try_compile() need only
to pass FortranCInterface_BINARY_DIR through the CMAKE_FLAGS option.

Brad King f64f9940af Teach FortranCInterface to verify languages
This module requires both C and Fortran to be enabled, so error-out if
they are not.

Brad King 80f0201b37 Rewrite FortranCInterface module
This is a new FortranCInterface.cmake module to replace the previous
prototype.  All module support files lie in a FortranCInterface
directory next to it.

This module uses a new approach to detect Fortran symbol mangling.  We
build a single test project which defines symbols in a Fortran library
(one per object-file) and calls them from a Fortran executable.  The
executable links to a C library which defines symbols encoding all known
manglings (one per object-file).  The C library falls back to the
Fortran library for symbols it cannot provide.  Therefore the executable
will always link, but prefers the C-implemented symbols when they match.
These symbols store string literals of the form INFO:symbol[<name>] so
we can parse them out of the executable.

This module also provides a simpler interface.  It always detects the
mangling as soon as it is included.  A single macro is provided to
generate mangling macros and optionally pre-mangled symbols.
