project (CudaOnlySeparateCompilation CUDA)

#Goal for this example:
#Build a static library that defines multiple methods and kernels that
#use each other.
#After that confirm that we can call those methods from dynamic libraries
#and executables.
#We complicate the matter by also testing that multiple static libraries
#all containing cuda separable compilation code links properly

#Having file4/file5 in a shared library causes serious problems
#with the nvcc linker and it will generate bad entries that will
#cause a segv when trying to run the executable
