[CMake] How to do that w/o LOCATION property of a target...

[Petr Kmoch]

Hi Alex.

I don't know if there is a better solution, but the following workaround
should work for you:

In your normal CMakeList, do `file(GENERATE OUTPUT location.cmake CONTENT
"set(TheLocation \"$<TARGET_FILE:TheTarget>\")\n")`.
Then, in the configured *.cmake script, do `include(location.cmake)`. The
location of the target will then be stored in the variable `TheLocation`.

Alternatively, generate just the location and use `file(READ)` instead of
`include()`, whichever suits you better.
