Add boost_root support to properties files (#7210) * Add boost_root support to properties files This commit implements `boost_root`, `boost_includedir`, and `boost_librarydir` variable support to native and cross properties files. The search order is currently environment variables, then these variables, and finally a platform-dependent search. * Add preliminary boost_root / boost_includedir tests Each test contains a fake "version.hpp", as that's how boost detection is currently being done. We look for this file relative to the root directory, which probably shouldn't be allowed (it previously was for BOOST_LIBRARYDIR but not for BOOST_ROOT). It also cannot help with breakage detection in libraries, however it looks like this wasn't getting tested beforehand. I've given the two unique version numbers that shouldn't be present in any stock version of boost (001 and 002). * Add return type to detect_split_root * Return empty list when nothing found in BOOST_ROOT, rather than None * Update boost_root tests * Create nativefile.ini based on location of run_project_tests.py * Add fake libraries to ensure boost_librarydir is being used * Require all search paths for boost to be absolute * Redo boost search ordering To better match things like pkg-config, we now look through native/cross files, then environment variables, then system locations for boost installations. Path detection does not fall back from one method to the next for properties or environment variables--if boost_root, boost_librarydir, or boost_includedir is specified, they must be sufficient to find boost. Likewise for BOOST_ROOT and friends. pkg-config detection is still optional falling back to system-wide detection, for Conan. (Also, fix a typo in test 33's nativefile) * Correct return type for detect_roots * Correct boost dependency search order in documentation * Print debug information for boost library finding, to resolve CI issues * Handle native/cross file templates in a more consistent way All tests can now create a `nativefile.ini.in` if they need to use some parameter that the testing framework knows about but they can't. * Pass str--rather than PosixPath--to os.path.exists, for Python35 * Look for boost minor versions, rather than boost patch versions in test cases * Drop fake dylib versions of boost_regex * Prefer get_env_var to use of os.environ * Correct error reporting for relative BOOST_ROOT paths * Bump version this appears in. Also, change "properties file" to "machine file" as that appears to be the more common language. 2020-07-21 22:40:29 +08:00			`[properties]`
