Operating System Version and Architecture

Describe Bug

If --project begins with a / but has . or .. components, then includes()-ed target()s will fail to find their files.

Given the following four files in /tmp/xmake-test:

1. s/s.cc:

   int s(int v) { return v; }

2. s/xmake.lua:

   target("s")
     set_default(false)
     set_kind("static")
     add_files("s.cc")

3. b/b.cc:

   int s(int);
   int main() { return s(42); }

4. b/xmake.lua:

   includes("../s")
   target("b")
     set_default(true)
     set_kind("binary")
     add_deps("s")
     add_files("b.cc")

and the following shell function to test things...

function test() {
  (rm -rf _ && mkdir _ && cd _; xmake config -v -D --project="$1" && xmake build -v -D)
}

then these work to build the b target() binary:

1. test /tmp/xmake-test/b -- absolute project path
2. (cd /tmp/xmake-test; test ../b)" -- relative (to /tmp/xmake-test/_) project path
3. (cd /tmp/xmake-test; test .././b)" -- similarly
4. (cd /tmp/xmake-test; test ../../xmake-test/b)" -- similarly

but these don't, because the final link step can't find the definition of s():

1. test "/tmp/xmake-test/./b"; xmake warns:

   warning: /tmp/xmake-test/s/xmake.lua:4: cannot match add_files("../../s/s.cc") in target(s)

2. test "/tmp/xmake-test/_/../b"; xmake warns:

   warning: /tmp/xmake-test/s/xmake.lua:4: cannot match add_files("../../../s/s.cc") in target(s)

Expected Behavior

xmake should treat all valid ways of referring to a --project path equivalently.
