ver 3.1 ADDBOOSTCMAKE_LINK_TYPE, fixed one if clause, more message(DEBUG...)

Arniiiii · Arniiiii · commit bfdd8495e963 · 2024-08-20T02:32:01.000Z
ver 3.1 ADDBOOSTCMAKE_LINK_TYPE ; fixed if clause ; if `CPM_LOCAL_PACKAGES_ONLY=1` emit more logs

Added ADDBOOSTCMAKE_LINK_TYPE, which allows specifying link type that the `add_boost` will use to a target.
By default it will use PUBLIC, unless your package is `INTERFACE`, in which case it will link with `INTERFACE`

Fixed `if` clause: there was `endif` after  `if(DEFINED BOOST_USE_MY_BOOST_DIRECTORY) ...` , not `elseif`

More message(DEBUG ...) . If you configure your project with `--log-level=DEBUG` , it will generate more DEBUG info.

Use my version of CPM until PR is accepted: now if used CPM_LOCAL_PACKAGES_ONLY, it will make CMake's `find_package` to emit error with description. Which is useful if correct boost version is found but failed to find a COMPONENT part. Previously CPM tried to just say "it failed. live with it` without logs.
