Stephen Kelly bd34963002 Refactor generation of shared library flags
CMAKE_SHARED_LIBRARY_<lang>_FLAGS has flags on various platforms for a
variety of purposes that are correlated with shared libraries but not
exclusive to them.  Refactor generation of these flags to use new
purpose-specific platform variables

  CMAKE_<lang>_COMPILE_OPTIONS_DLL
  CMAKE_<lang>_COMPILE_OPTIONS_PIC
  CMAKE_<lang>_COMPILE_OPTIONS_PIE

Activate the DLL flags specifically for shared libraries.  Add a new
POSITION_INDEPENDENT_CODE target property to activate PIC/PIE flags, and
default to true for shared libraries to preserve default behavior.
Initialize the new property from CMAKE_POSITION_INDEPENDENT_CODE to
allow easy global configuration in projects.

Although the default behavior is unchanged by this refactoring, the new
approach ignores CMAKE_SHARED_LIBRARY_<lang>_FLAGS completely.  We must
leave it set in case projects reference the value.  Furthermore, if a
project modifies CMAKE_SHARED_LIBRARY_<lang>_FLAGS it expects the new
value to be used.  Add policy CMP0018 to handle compatibility with
projects that modify this platform variable.

Add a PositionIndependentCode test on platforms where we can get
meaningful results.

Brad King 470f39cf4e VS: Restore header files marked as OS X Framework content (#13196)
Header files listed in a target's PUBLIC_HEADER or similar properties
are marked as OS X Framework content.  Refactoring performed by

 commit 11d9b211 (Add cmGeneratorTarget to represent a target during generation, 2012-03-07)
 commit 45c2f932 (Simplify cmMakefileTargetGenerator using cmGeneratorTarget, 2012-03-07)
 commit 328c0f65 (Simplify cmVisualStudio10TargetGenerator source classification, 2012-03-19)

and related commits accidentally removed such files from treatment as
normal header files by the VS generator (generators other than Makefiles
and Xcode).  Move handling of such files out of cmGeneratorTarget and
back to cmMakefileTargetGenerator.  The central cmGeneratorTarget
classification will always treat them as header or extra sources.

Brad King c403f27a2d Add $<TARGET_OBJECTS:...> expression to use an object library
For now do not allow an OBJECT library to reference other object
libraries.  Teach cmTarget::ComputeLinkImplementation to include the
languages of object libraries used by a target.

Brad King 3baaf6ccec Pre-compute object file names before Makefile generation
Add a virtual cmGlobalGenerator::ComputeTargetObjects method invoked
during cmGeneratorTarget construction.  Implement it in the Makefile
generator to pre-compute all object file names for each target.  Use
the results during generation instead of re-computing it later.

Brad King afb00fef19 Add CMAKE_GNUtoMS option to convert GNU .dll.a to MS .lib
Teach the Windows-GNU.cmake platform file to look for Visual Studio
tools matching the target ABI.  Add an extra step to the link command
for shared libraries and executables that export symbols and on which a
new GNUtoMS property is set (initialized by the CMAKE_GNUtoMS option).
Tell the GNU linker to output a module definition (.def) file listing
exported symbols in addition to the GNU-format import library (.dll.a).
Pass the .def file to the MS "lib" tool to construct a MS-format DLL
import library (.lib).

Teach the install(TARGETS) command to install the MS import library next
to the GNU one.  Teach the install(EXPORT) and export() command to set
the IMPORTED_IMPLIB property pointing at the import library to use the
import library matching the tools in the importing project.

Define a "Fortran_FORMAT" target and source file property.  Initialize

values "FIXED" and "FREE" to indicate the source file format.  Append
corresponding flags to the compiler command line.

Brad King 4e2185cbd0 Make std::map usage more portable in language=>flags/defines maps
Older versions of GCC, the HP compiler, and the SGI MIPSpro compiler do
not like the use of make_pair in this case and the conversions it
requires:

  a value of type "const char *" cannot be used to initialize an entity
  of type "char [1]"

  /usr/include/g++-3/stl_pair.h:68: assignment of read-only location

Instead use a map lookup pattern already used throughout the rest of our
source tree.

Brad King 5622a16f1f Make Fortran $obj.provides.build targets not .PHONY
Commit 60cd72d0 (Cleaned up generation of symbolic rules, 2006-02-15)
incorrectly made these Makefile targets .PHONY even though the build
rule touches an actual file.  Correct it so that the copy_f90_mod and
touch steps do not happen on every "make".

Brad King ab9ebb017e Fix Fortran .mod timestamps with Cray compiler
Commit 34e1ac24 (Create Fortran info variables for .mod behavior,
2010-11-12) incorrectly taught GetFortranModuleDirectory to return a
relative path.  We really want to use "." as the module directory only
as a workaround for compilers that do not do so by default.  Therefore
we need this default only when generating the compiler command line and
not when scanning dependencies.

Revert the previous change to GetFortranModuleDirectory and apply the
change only at one of its call sites.

Brad King c592df8377 Tru64: Use full-path include directives in Makefiles (#10569)
Tru64's make(1) resolves relative paths in "include" directives with
respect to the includer.  This is inconsistent with all other known make
tools.  Note that this make tool treats the path literally so we cannot
use our standard FULL path code which escapes spaces.  Instead qualify
the paths with $(CMAKE_BINARY_DIR) to avoid the problem.

Brad King f9268c9c81 Use platform variable for response file flag
Create platform variable "CMAKE_<LANG>_RESPONSE_FILE_LINK_FLAG" to

Brad King 87f0853941 Use forward slashes for objects in response files
Response files are parsed by tools, not by shells.  We teach
cmLocalGenerator::Convert() a new "RESPONSE" output format and use it
for objects listed in response files.  It does not do special slash or
MSYS root translation like the "SHELL" format does.  This is necessary
for GNU tools on Windows to understand response file content.

See issue #10401.

Brad King c87a35a326 Do not call CollapseFullPath for PDB file names
Some vendor tools convert PDB file names given on the command line to
lower-case before creating the file.  When CMake places a mixed-case PDB
file name into the build system, the file does not exist the first time
and it is written with mixed case.  After the first build though the
native tool has created a lower-case version of the file.  If CMake does
CollapseFullPath again, the file exists so the actual-case lookup gets
the lower-case name.  This causes the build files to change so the
project rebuilds.

The solution is to avoid calling CollapseFullPath for files generated by
the build.  In the case of PDB files we already construct them from
paths that have been collapsed, so we can just skip the call altogether.
See issue #9350.

This feature will allow scripted builds to avoid the cost since they do
not need detailed information anyway.  This replaces the RULE_PROGRESS
property created earlier as it is more complete.  See issue #8726.
