[PATCH] D84334: [flang] Version information in flang/f18

[Richard Barton via Phabricator via llvm-commits]

Steve's patch works for me (cmake 3.17). @coti , your error message looks like what would happen if you replaced both definitions of {{include}} with the {{target_include_directories}} call. {{include}} is set up to the location of pre-built modules and is used in the compilation of said modules and then pre-processed into the flang.sh script. You still need that as well as setting {{target_include_directories}} to tell CMake where f18_version.h is when building f18.cpp.

Note for future (not part of this patch) those modules ought to end up in the lib directory of the install not the include directory. Clang puts similar headers in lib/clang/<version>/include and we should ultimately do the same for Flang. I think the include dir in the installation is for LLVM header files, e.g. if you wanted to use the LLVM libraries in some project or other.
