[CMake] how to specify a different source directory

[aaron.meadows at thomsonreuters.com]

That sounds about right to me.  (though personally, I like to make my
tests include the files they are testing by linking to a library
containing them...)


If you wanted to abstract the location away from the test code, you
could set a variable containing the source files in a higher (or
earlier) CMake scope and use that variable to within the deeper scope to
add them to your executable.


/foo/CMakeLists.txt

#[...]

  set(FilesToIncludeInTestExe
      ${CMAKE_CURRENT_LIST_DIR}/file1.cpp
      ${CMAKE_CURRENT_LIST_DIR}/file2.cpp
      ${CMAKE_CURRENT_LIST_DIR}/file3.cpp
      ${CMAKE_CURRENT_LIST_DIR}/file4.cpp
    )

#[...]

/foo/foo_test/CMakeLists.txt

#[...]

   add_executable(foo_test  ${fooTestFiles} ${FilesToIncludeInTestExe} )

#[...]

Some other alteratives might be to set a Global or target property in
the parent CMakeLists.txt and read it in the child one.

OK I figured out when I pass in the source file to  add_executable, I
just need to prefix the source file with "../"

Is this the proper way to do it, or should I be using another cmake
command to declare a source folder?

Thanks,
