Dear CMakers, I want to have all my C++ headers self-sufficient (self-contained), i.e., a header can be included without additional includes. This is not only handy but also part of Google's C++ styleguide [2].
It would be great to have a make target (let's call it headercheck), that can check for this, by compiling a simple test.cc file for each current_header.h: #include <config.h> #include "current_header.h" #include "current_header.h" Additionally it would be great to have such a target for every folder (checking all headers recursively) and every header that is explicitly passed as an argument. We tried this with CMake: We generate a test.cc file per header and create a library for every cc file. The problem is, that we get hundreds of additional targets, we generate a lot of folders and files which can increase our build directory size by an order of magnitude and it does not work properly on a per file or per directory basis. What do you think, is there a good way to have such a target headercheck with CMake? Or would it be better to include it as a CTest? Or better as an external (bash) script as proposed in [1]? If it can be done in a good way with CMake, would it be of interest to include it as a feature in CMake? Or as an external project similar to UseLATEX.cmake?
