Building C++: It Doesn't Have to be Painful!
summary
reMarkable rewrites its build system into a CMake library called rho that claims to make C++ builds declarative and incremental, handling platform quirks, feature flags, dependencies and installation; it integrates with VC package integration and uses a tiny rho boot file to opt projects in. rho implements source discovery globs, injects at toolchain/target/install points, runs its CMake-function tests in CI, and ships enough defaults to replace boilerplate. Known limits: vcpkg baselines and slow local installs; plan adds an add_subdirectory for local dev.
