[CMake] Implicit toolchain file usage
Hi, I have been pondering for a while if it was possible (theoritically, and then practically) to get the toolchain fine defined inside one (main?) of the cmake files? I have been using the -DCMAKE_TOOLCHAIN_FILE=my-toolchain-file.cmake option, but I think this can become duplicated easily. That is because most of the time the developers, packagers, or users may have to define the platform to build for on the command line anyway. Hence, the toolchain file detection and usage could be implicit. I have also imported my toolchain file into the project because it is a very short file, and really not a big burden. I understand that the toolchain files are specified by this file, so this should be put into an early stage of the build procedure for sure. Otherwise, everyone has to deal with it separately, which is undesirable, I believe. Sometimes, it may make sense to customize this on your own, but there could be a fallback provided by the project developers implicitly inside the build system of the given project. I think, this would be a great thing to have. Is it already available now like just simple define (implicit equivalence of the -D) or so?
