Get file of current macro file in CMake

Question

I'm writing a .cmake file that handles a bunch of stuff and needs access to an executable in a fixed relative path to the .cmake file. In this instance, the orgianization looks like this:

CMakeLists.txt 
   - cmake
       - tools.cmake 
       - bin
           - exectuable.exe

The issue is that tools.cmake is included using include and thus, CMAKE_CURRENT_SOURCE_DIR returns the directory of the CMakeLists.txt. The reason I don't want to hardcode the path is that I want to put the tools.cmake and binary in a separate GIT repository and I don't want to force the user to place it in some specific folder.

Only solution I can come up with right now is to supply a function that sets and stores the path to tools.cmake. That's not really elegant.

Are `CMAKE_CURRENT_LIST_FILE` and `CMAKE_CURRENT_LIST_DIR` the variables you are looking for? — vre, Jun 14 '18 at 14:50
@vre as described, they are not returning the `tools.cmake` but the `CMakeLists.txt` in which `tools.cmake` is included. — ruhig brauner, Jun 14 '18 at 14:54
I'm get it to work by having the user store the variable to the path manually using properties. But I'ld really like to skip that step. — ruhig brauner, Jun 14 '18 at 15:04

CMAKE_JUCE_TOOLS_PATHdoes not return the correct path within functions or macros in tools.cmake but it results in the correct path outside any function. So one can us

set(PATH_TO_TOOLS_CMAKE ${CMAKE_JUCE_TOOLS_PATH})

to store the path while it can be accessed in a variable and than access PATH_TO_TOOLS_CMAKE in functions and macros
