bug in global variables substitution

[killerbot]

it seems when you use a global variable in the file specifications of a project like :

      <Unit filename="${#cmakebuild}/foo/bar/test.cpp" />

then the global variable does not get substituted, doing similar thing for the include directories does work, there substitution does occur.

Writing cbp files by hand is not supported.
Projects have massive amounts of file, so doing replace marcos on every path won't be any good for load times, which aren't really good even without it.
