Yes, that’s the theory.

In practice it never worked on Mac. I’m using cmake to generate a Xcode project to debug the LyX code.

ATM it doesn’t work on the new Mac server I’m using. The error message is as follows:
===========
CMake Error in src/tex2lyx/CMakeLists.txt:
  The custom command generating

    /Users/lyx/Development/lyx-build/cmake/2.4.0dev/src/tex2lyx/test/Tex2lyxFilesUpdated

  is attached to multiple targets:

    cleanupdatetex2lyxtests
    updatetex2lyxtests

  but none of these is a common dependency of the other(s).  This is not
  allowed by the Xcode "new build system“.
===========

This error message is presented for every CMakeLists.txt file in LyX’s tree.
