IMHO this workaround is way to hackish for a paid tool. The proper thing
for Bullseye would be to provide a touchless way of intercepting all
compiler invocations like for example Fortify or Coverity provides. You
would be able to call it like this:

  $ bullseye xcodebuild

It would trace compiler invocations from xcodebuild and all childs.

I have not tested it, but maybe you could add
   -DCMAKE_C_COMPILER=$(xcrun -find clang) -DCMAKE_CXX_COMPILER=$(xcrun
-find clang++)

to the cmake command line at configuration time.
