Yangqing Jia ab638020f8 Backport FindCUDA functionalities from CMake
Summary:
This is in principle similar to #1612 and is tested on Windows 2017. CMake passes, although there are still bugs in the MSVC compiler that prevents cuda to compile properly.

The difference between this and #1612 is that this diff explicitly puts the CMake files into a separate folder and uses a MiscCheck.cmake chunk of code to test whether we need to include them. See README.txt for more details.

# FindPackageMessage
# ------------------
#
#
#
# FIND_PACKAGE_MESSAGE(<name> "message for user" "find result details")
#
# This macro is intended to be used in FindXXX.cmake modules files. It
# will print a message once for each unique find result. This is useful
# for telling the user where a package was found. The first argument
# specifies the name (XXX) of the package. The second argument
# specifies the message to display. The third argument lists details
# about the find result so that if they change the message will be
# displayed again. The macro also obeys the QUIET argument to the
# find_package command.
#
# Example:
#
# ::
#
# if(X11_FOUND)
# FIND_PACKAGE_MESSAGE(X11 "Found X11: ${X11_X11_LIB}"
# "[${X11_X11_LIB}][${X11_INCLUDE_DIR}]")
# else()
# ...
# endif()
function(FIND_PACKAGE_MESSAGE pkg msg details)
# Avoid printing a message repeatedly for the same find result.
if(NOT ${pkg}_FIND_QUIETLY)
string(REPLACE "\n" "" details "${details}")
set(DETAILS_VAR FIND_PACKAGE_MESSAGE_DETAILS_${pkg})
if(NOT "${details}" STREQUAL "${${DETAILS_VAR}}")
# The message has not yet been printed.
message(STATUS "${msg}")
# Save the find details in the cache to avoid printing the same
# message again.
set("${DETAILS_VAR}" "${details}"
CACHE INTERNAL "Details about finding ${pkg}")
endif()
endif()
