Currently documentation build fails if PDF generation tools are available in the build environment.
The problem is caused by CMAKE_MAKE_PROGRAM not being set when the document creation targets are defined. As a result CMake generates “empty” targets which do not execute the final step of PDF generation.
The problem was triggered by project re-organization (moving secure fw build out of app territory) . The issue could have been avoided if the document generation cmake files did not missed checking the CMAKE_MAKE_PROGRAM which is an input of them.
