generator expressions in the CUDA_NVCC_FLAGS variable.

Brad King 72a97b7a76 FindCUDA: Fix regression in separate compilation (#16027)
Since commit v3.5.0-rc1~47^2 (FindCUDA: Support special characters in
path, 2016-01-15) our add_custom_command calls use VERBATIM so that
CMake will automatically quote special characters correctly.  Fix the
separate compilation code path to not add its own quoting when the
VERBATIM option will be used.

Brad King 1911cda03e FindCUDA: Fix regression under Visual Studio generators
Since commit v3.5.0-rc1~47^2 (FindCUDA: Support special characters in
path, 2016-01-15) our add_custom_command calls use VERBATIM so that
CMake will automatically quote special characters correctly.  However,
this breaks the special `$(VCInstallDir)` placeholder used with Visual
Studio generators.  Since we do not support preservation of such
placeholders with VERBATIM (see issue #15001) we must fall back to not
using VERBATIM when the placeholder is used.

A better fix would be to stop using `$(VCInstallDir)` and use the value
of `CMAKE_${CUDA_C_OR_CXX}_COMPILER` instead, but that will require
additional semantic and documentation changes.  For now simply fix the
regression with the above approach.

There is the global CMAKE_DL_LIBS setting which can be used instead. There are
even platforms where this is either empty because those functions are part of
the libc or is called entirely different, so this code wouldn't work reliable
anyway.

James Bigler 8313de2d5a FindCUDA: Allow setting CUDA_SOURCE_PROPERTY_FORMAT for non-.cu files.
A previously undocumented feature allowed overriding the format
specified to CUDA_WRAP_SRCS with a source file property called
CUDA_SOURCE_PROPERTY_FORMAT.  I added documentation for this feature as
well as added the ability to let nvcc compile any file regardless of
type if this property was found.

In addition, I also fixed a couple of bugs with the calls to
_cuda_get_important_host_flags that weren't garding the arguments with
"" to prevent empty values from causing errors.

James Bigler 99abebdea0 FindCUDA: Handle c++11 host flag
If the host flags contain a c++11 flag (at least for gcc), then we can't
automatically propagate to nvcc it using -Xcompiler.  This is because
nvcc can't use any C++ only flags.  Instead we find this flag and add it
to nvcc's flags (it has a special flag for dealing with c++11 code) and
remove it from the host flags.

James Bigler 7fea2b77df FindCUDA: Use the static CUDA runtime library if available (#15482)
Beginning in CUDA 5.5 a static version of the cuda runtime library
became available.  Since nvcc defaults to using this library over the
shared version, FindCUDA will also default to using this version.  There
are many advantages to using the static version (most importantly to
avoid conflicts with multiple versions when building a CUDA based
library).  Offer a CUDA_USE_STATIC_CUDA_RUNTIME option to control
this behavior.

Adam Strzelecki 32bcec5fab FindCUDA: Fix OSX Clang & no C language enabled
When setting default CUDA_HOST_COMPILER we must dereference CMAKE_C_COMPILER,
i.e. /usr/bin/clang should be used instead /usr/bin/cc which is symlink.
Otherwise CUDA thinks it is GCC and issues -dumpspecs which is unknown option
to Clang.

Also in case neither CMAKE_C_COMPILER is defined (project does not use C
language) nor CUDA_HOST_COMPILER is specified manually we should skip -ccbin
and let nvcc use its own default C compiler.

Daniele E. Domenichelli 81a3f22882 Do not change minimum required version in modules
Some modules change CMake minimum required version when they are
included. For example:

  cmake_minimum_required(VERSION 2.8.12)
  message("${CMAKE_MINIMUM_REQUIRED_VERSION}")
  include(CheckTypeSize)
  message("${CMAKE_MINIMUM_REQUIRED_VERSION}")

will produce the following output:

  2.8.12
  2.6

This patch ensures that when you include a CMake module the minimum
required version and the policies set are left unchanged.

Brad King ef27fa6760 FindCUDA: Always list custom command outputs in their targets
CMake's intended interface for linking to explicit object files (marked
with EXTERNAL_OBJECT) is that only those listed as target sources should
be linked.  Drop FindCUDA's attempt to hide the .obj files from VS IDE
project files, which depends on VS-version-specific behavior of linking
custom command outputs that happen to be named "*.obj".  CMake puts
external object files in a dedicated source group anyway.
