Subject: Add CMakeAddFortranSubdirectory to use MinGW gfortran in VS

This patch adds a new module that allows for easy integration of MinGW
gfortran and the Visual Studio compiler. It is done in a function called
cmake_add_fortran_subdirectory. The patch also includes a test for this
feature.

+# - Use MinGW gfortran from VS if a fortran compiler is not found.
+# The 'add_fortran_subdirectory' function adds a subdirectory
+# to a project that contains a fortran only sub-project. The module
+# will check the current compiler and see if it can support fortran.
+# If no fortran compiler is found and the compiler is MSVC, then
+# this module will find the MinGW gfortran.  It will then use
+# an external project to build with the MinGW tools.  It will also
+# create imported targets for the libraries created.  This will only
+# work if the fortran code is built into a dll, so BUILD_SHARED_LIBS
+# is turned on in the project.  In addition the GNUtoMS option is set
+# to on, so that the MS .lib files are created.
+# Usage is as follows:
+# cmake_add_fortran_subdirectory(
+#   <subdir>                 # name of subdirectory
+#    PROJECT <project_name>  # project name in sbudir toplevel CMakeLists.txt
+#  ARCHIVE_DIR <dir>         # .lib location relative to root binary tree (lib)
+#  RUNTIME_DIR <dir>         # .dll location relative to root binary tree (bin)
+#  LIBRARIES lib2 lib2    # names of libraries created and exported
+#  LINK_LIBRARIES            # link interface libraries for LIBRARIES

Subject: CMakeAddFortranSubdirectory: Allow full paths to directories

Fix the implementation to allow full paths with spaces.  Change the
interpretation of relative paths to be with respect to the current binary
directory.  This matches the convention used in ExternalProject.  Test
both full and relative paths in the VSGNUFortran test.

Subject: CMakeAddFortranSubdirectory: Find gfortran in PATH

In the find_program(MINGW_GFORTRAN) call use the PATHS option for
hard-coded guesses instead of HINTS.  This allows the user environment
to override the guesses and corrects usage of the command options.

Verify that MINGW_GFORTRAN not only points to a MinGW gfortran but also
one that compiles for the target architecture.  This prevents using a
32-bit gfortran in a 64-bit MSVC build.

Subject: CMakeAddFortranSubdirectory: Make IMPORTED targets GLOBAL

cmake_add_fortran_directory uses imported targets when using the
mingw fortran compiler. This change makes those targets global
in scope so they act just like the real targets that exist when
a fortran compiler exists and regular add_subdirectory is used.

Subject: CMakeAddFortranSubdirectory: Always parse arguments

Parse arguments even in add_subdirectory() mode to validate them.

Subject: CMakeAddFortranSubdirectory: Add NO_EXTERNAL_INSTALL option

We do not yet support "make install" in the external project case.
Document this explicitly in the interface.  Require the caller to use an
option to "disable" the unsupported behavior.  This will allow us to add
the behavior by default in the future without clobbering existing
projects that handle the installation themselves.
