Summary0016096: FindCUDA requires dynamic runtime even if building statically
DescriptionIn https://gitlab.kitware.com/cmake/cmake/commit/7fea2b77df2d70283f4918a8ff52836dbc68db6b, [^] support was added to use the static CUDA libraries. The script still checks for and requires that the dynamic libraries are installed in order to build successfully, though they are not needed for a static build.
Steps To Reproduce - Setup a machine on which to use build CUDA, which has the static libraries available
 - Remove or delete cudart.so
 - Create a cmake script with `find_package(CUDA REQUIRED)`
 - When run, the script will fail with:

CMake Error at /usr/local/share/cmake-3.5/Modules/FindPackageHandleStandardArgs.cmake:148 (message):
  Could NOT find CUDA (missing: CUDA_CUDART_LIBRARY) (found version "7.5")
Call Stack (most recent call first):
  /usr/local/share/cmake-3.5/Modules/FindPackageHandleStandardArgs.cmake:388 (_FPHSA_FAILURE_MESSAGE)
  /usr/local/share/cmake-3.5/Modules/FindCUDA.cmake:949 (find_package_handle_standard_args)
  imagery/CMakeLists.txt:43 (find_package)
Additional Information
The dynamic library is located at:

 725 cuda_find_library_local_first(CUDA_CUDART_LIBRARY cudart "\"cudart\" library")

The static library is located at:

 734 cuda_find_library_local_first(CUDA_cudart_static_LIBRARY cudart_static "static CUDA runtime library")

Later in the script, the variable for the dynamic library is required, even if the library itself is not required for a successful build.
