doc/CMakeLists.txt now sets a variable indicating that we either have, or can build, each individual man page. And when we call our installed_program() function to mark a program as official enough to put in 'make install', that function also installs the man page similarly if it exists, and warns if not. For the convenience of people building-and-installing from the .tar.gz we ship, I've arranged that they can still get the man pages installed without needing Halibut: the previous commit ensured that the prebuilt man pages are still in the tarball, and this one arranges that if we don't have Halibut but we do have prebuilt man pages, then we can 'build' them by copying from the prebuilt versions.
