Fix magic_enum discovery for build-dir CDT_ROOT#44
Open
Conversation
When using a CDT build directory as CDT_ROOT (instead of a proper install prefix), magic_enum headers are not in CDT_ROOT/include but in the vcpkg_installed directory. Add vcpkg path as a fallback in find_cdt_magic_enum using VCPKG_INSTALLED_DIR and VCPKG_TARGET_TRIPLET. Also uncomment the CDT_CONTRACT_INCLUDE_PATH search path and add a diagnostic message when the contract include path is active.

Set CDT_CONTRACT_INCLUDE_PATH from vcpkg include directory and forward it to the CDT toolchain so contract builds can locate vcpkg-provided headers (e.g. magic_enum) when using a CDT build directory as CDT_ROOT. Also reformats CDT_CMAKE_ARGS for readability. Companion to Wire-Network/wire-cdt#44.

One note CDT_CONTRACT_INCLUDE_PATH could be a semicolon delimited list; I'd create a nested macro invoked as find_in_cdt_contract_paths(_matched_include_path MATCH magic_enum [DIRECTORY|FILE] [MATCH_VAR_FULL _full_matched_path_with_suffix])
