Develop branch: error configuring as subproject

[dmdunla]

When configuring Kokkos as a subproject, there is an error due to the fact that no project has been set. The error started with commit e949642, as the removal of the "${}" around PROJECT_NAME means that the code that sets the project inside the conditional will never execute. Without the project being set, "${Kokkos_BINARY_DIR}", in turn will not be set and thus there is an error in cmake/kokkos_install.cmake (line 10) as shown below.

$ cmake .. -DKokkos_ENABLE_SERIAL:BOOL=ON

This will be fixed in #3135.
