includes doesn't work with $(env VARIABLE)

[mactul]

Hello !

I have a set of functions in the description scope that I use in all my xmake.lua

I want to write something like this

includes("$(env XMAKE_TOOLS)/tool_xxx.lua")

But unfortunately, it seems that includes doesn't support the $(env XXX) syntax.
I can't write the absolute path because the project is meant to be built on multiple machines and multiple operating systems, so the absolute path is always different...

Does a workaround exists to solve my problem or am I screwed ?

Thank you in advance,
Mactul

includes(path.join(os.getenv(XMAKE_TOOLS), "tool_xxx.lua"))
