Simplify it, and generate it in the build dir, rather than the source dir.
For one, keeping
common/cmake/build-info-gen-cpp.cmake
out of the maincmake/
is confusing, especially since it depends oncmake/build-info.cmake
there.Also the
add_custom_command(cmake ... -P script)
didn't inherit any variables which means they had to be passed on explicitly. I needed to add variables but this became convoluted so I simplified it instead.I assume that the
add_custom_command(cmake)
was only added for the dependency on.git/index
, I found a workaround for that. This allowed me to drop the complicated stuff and reduce this to aconfigure_file
which now also writes to the build dir instead of the source dir.
