SOURCE_DATE_EPOCH was created for use by packagers where tools already wrap the build. By making it an environment variable packagers could jump through any number of build system layers with no patching. Build systems configure compilers with command-line flags, not environment variables. If you want to do this from within the build system then GCC could be taught a new option for that. You could try hacking it with `CMAKE_<LANG>_COMPILER_LAUNCHER`: https://cmake.org/cmake/help/v3.13/variable/CMAKE_LANG_COMPILER_LAUNCHER.html e.g. -DCMAKE_C_COMPILER_LAUNCHER='env;SOURCE_DATE_EPOCH=1' or ```cmake set(CMAKE_C_COMPILER_LAUNCHER env SOURCE_DATE_EPOCH=1) ``` -Brad -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
