* Support CMake 4 CMake 4 has removed compatibility with CMake < 3.5 Bumping minimum required version to 3.5 enables CMake 4 to build this code. * Move header into subdir * Improve CMake setup This commit configures and installs CMake metadata files. This also provides the namespaced ALIAS target `cpp-subprocess::subprocess`. * Update README with CMake instructions * Update include paths in tests
