[vcpkg] Add Supports: field. Use contents of triplets instead of names for dependency resolution. (#8601) * remove unfinished "supports" tag * extract "supports" from control files But do nothing with the value * Start `Supports` documentation * Use Supports in a bunch of control files I only tried matching the already existing logic in the portfile.cmake. * Cmake var provider (#8) * Cmake var provider (#9) * fix windows build (#10) * Add missing files to build * Fix test (#11) * adding hooks for cmake variables in expressions * Adding hooks for 'supports' in CI test * Fix test (#12) * Add overrides to evaluation environment * use "supported" tag in CI testing * cleanup comment * Fix issues with PR * [var_provider] Get library linkage variables from triplet * Fix compilation errors in tests * Add unimplemented functions * Fix unit tests part 1 * Fix issue when buildtrees dir does not exist * Change binary output hash * Fix handling of * feature * Add core feature when using * * Do not add Default-Features when installing 'core' * [vcpkg] WIP. 6 failing tests. * [vcpkg] WIP. 1 failing tests. * [vcpkg] WIP. 0 failing tests. * [vcpkg] Removed 'remove_graph'. 0 failing tests. * [vcpkg] Removed 'install_graph'. 0 failing tests. * [vcpkg] Remove AnyAction; replace with ActionPlan * [vcpkg] Minor cleanup. * [vcpkg][z3][qt5-connectivity][qt5-purchasing] Improve error messages while parsing. Fix a few trivial port issues. * [vcpkg] Work around ICE with MSVC v140 * [vcpkg] Add purge on fail to decompress for CI * [vcpkg] Fix parsing of nested parentheses in qualifiers * [vcpkg] Fix Linux builds (explicit qualification in declaration) * [vcpkg] Fix Build-Depends implying default features. Fix qualified dependencies regression. * [mmx] Add to skip list and full rebuild -- mmx causes problems by installing 'sched.h' * [libpqxx][mqtt-cpp] Prevent installing include/CMakeLists.txt * [cppitertools] Fix installed include namespace (should be include/cppitertools) * [libsoundio] Move headers into soundio/ subdirectory as per original cmake * [ci.baseline] Temporarily skip charls due to conflict with dcmtk * [vcpkg] Add restricted include files post build check -- bump global abi version * [libsoundio] Hotfix stray line in portfile * [vcpkg] Fix regression: CMake information was not being displayed for build-and-install actions * [jsonnet] Fix installation of internal headers; use system nlohmann-json * [grpc][upb] Teach grpc to use packaged upb. Add find_package(upb). Remove inappropriate upb features. * [zfp] Move problematic 'include/bitstream.h' to 'include/zfp/bitstream.h' * [x265] Bump control version to trigger rebuild after zfp conflict * [akali] Disable parallel configure * [dirent][dlfcn-win32][getopt-win32][pthreads] Grandfather into VCPKG_POLICY_ALLOW_RESTRICTED_HEADERS * [ci.baseline] Update baseline for improved upb support * [tgui] Disable parallel configure * [libiconv] Enable VCPKG_POLICY_ALLOW_RESTRICTED_HEADERS * [aws-sdk-cpp] Disable parallel configure * [vcpkg] Implement policy VCPKG_POLICY_ALLOW_RESTRICTED_HEADERS * [aws-sdk-cpp] Fix amount of escaping semicolons -- Note: I do not know the root cause requiring this change * [libodb-sqlite] Fix configuring into source directory * [gettext] Grandfather into VCPKG_POLICY_ALLOW_RESTRICTED_HEADERS * [libodb] DISABLE_PARALLEL_CONFIGURE * [vcpkg] Add 'config.h' and 'local.h' to restricted header list * [mcpp] Remove unused and problematic include 'config.h' from installed files * [teemo] Move installed headers into subdirectory to prevent conflicts with x265 * [ci.baseline] Update current OSX. Skip libmesh on all platforms due to heavy conflicts. * [vcpkg] Add 'slice.h' as a restricted header * [osg] Improve accuracy of dependencies (disable some, add some to Depends) * [vcpkg] Skip invoking a subprocess for 0 specs in load_tag_vars * [ci.baseline] Skip mongo-c-driver on osx due to flakiness * [teemo] Fix incorrect include file read * [osg] Fix dependency typo: glut -> freeglut * [vcpkg] Recover some lost performance with the addition of vcpkg_get_tags. A huge performance cost was loading the triplet files over and over; instead, we splice the sources into a macro and load it once, then just call that macro for each port. Remove use of hashing because we aren't cross-process-safe anyway (global static will do instead). * [vcpkg] Change Supports atom 'windows' to include UWP. Improve Supports field documentation. * [vcpkg] Add docs for VCPKG_ENV_PASSTHROUGH and VCPKG_DEP_INFO_OVERRIDE_VARS * Fix typo Co-authored-by: Curtis J Bezault <curtbezault@gmail.com> Co-authored-by: Victor Romero <romerosanchezv@gmail.com> Co-authored-by: Robert Schumacher <roschuma@microsoft.com>
