#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
