#Goal for this example:

#build a cpp dynamic library base
#build a cuda static library base that uses separable compilation

#build a cuda dynamic library that uses the first dynamic library
#build a mixed cpp & cuda dynamic library uses all 3 previous libraries

#lastly build a cpp executable that uses this last cuda dynamic library

#this tests that we can properly handle linking cuda and cpp together
#and also building cpp targets that need cuda implicit libraries

#verify that we can pass explicit cuda arch flags
