CUDA target doesn't respect external packages' add_includedirs

[chenzhekl]

Per the title, when compiling *.cu files with nvcc, include directories set by external packages are not added as -Ixxx to the compiler flags.

This should be no problem. I have tested it before.

You can try compiling this example. https://github.com/tboox/xmake/tree/master/tests/projects/cuda/console

If there is still this problem, I'll look at it later.

It's a bit different from my case. I created a directory thirdparty to store dependencies, and called add_packagedirs("thirdparty") in the project's xmake.lua.

In one of the denpendencies:

-- In xmake.lua

option("xxx")
    -- ...
    -- This line doesn't work.
    add_includedirs("xxxxx")
    -- ...

and in the project's xmake.lua:

-- ...
add_packagedirs("thirdparty")
-- ...

target("xxx")
    -- ...
    -- This line doesn't make include directories from "xxx" visible to `nvcc` compiler.
    add_packages("xxx")
    -- ...

Do I misunderstand something?

I have fixed it, you can update dev branch and try it again. 3cd27c6

@waruqi Thank you for such a quick fix! I'll test it tomorrow in the lab.

Works as expected now.
