Christian Blichmann	948b75efe9	CMake cleanups ... - Bump minimum requred version to 3.12 (Ubuntu Cosmic LTS) - Rename `SAPI_USE_?` options to `SAPI_DOWNLOAD_?` - Improve detection of Python 3 - Use platform independent static library suffixes for `find_library()` PiperOrigin-RevId: 281727467 Change-Id: I45596b6ba08e4f8201d8dcde19a03baf825b83ec	2019-11-21 05:17:25 -08:00
Christian Blichmann	d91879f752	Ensure compatibility with CMake 3.10 ... This fixes some CMake-3.12+-isms, like `list(JOIN ...)` and setting link properties on OBJECT libraries. PiperOrigin-RevId: 265033725 Change-Id: I0ee1ec0e1b1097ea8226ad6fdeff794a97c2881b	2019-08-23 05:08:55 -07:00
Christian Blichmann	3c51348aaf	Enable CMake projects to consume Sandboxed API via add_subdirectory() ... This change moves away from a classical superbuild which downloads and builds at build time. Instead, we now follow a "Fetch Content" workflow (available as FetchContent in CMake 3.11+) and download dependencies at config time. Rationale: Superbuild projects have the disadvantage that projects cannot directly access their individual declared targets. This is not a problem with regular libraries, as those are usually/supposed to be installed. With Sandboxed API, this is not desirable, as it has dependencies like Abseil and glog, which are almost always consumed by including their source tree using add_subdirectory(). Fixes #10 and makes external embedding easier. PiperOrigin-RevId: 260129870 Change-Id: I70f295f29a6e4fc8c330512c94b01ef10c017166	2019-07-26 05:51:08 -07:00
