# When cross-compiling, run the generator executables that were installed by
# the host build of tdlib[tools] (declared as a host:true dependency in
# vcpkg.json).  Running them directly avoids a cmake sub-invocation and
# therefore sidesteps the Windows ARM64 problem where a cmake subprocess
# inherits the vcvarsall cross-compiler and produces the wrong architecture.
if(VCPKG_CROSSCOMPILING)
    # When updating this port to a new tdlib version, verify the cross-compile
    # generator invocations below still match what the upstream build does:
    #
    #  1. TL-schema list (the foreach over _scheme):
    #     Compare against the tl_generate_tlo custom target in
    #     td/generate/CMakeLists.txt — every .tl file passed to tl-parser
    #     there must be listed here.
    #
    #  2. MIME-type step (generate_mime_types_gperf + gperf):
    #     Driven by tdutils/generate/CMakeLists.txt.  Check that the input
    #     file (mime_types.txt), the two .gperf output names, and the two
    #     gperf output .cpp names still match that file.
    #
    #  3. Generator executables (the foreach over _gen):
    #     Must include every add_executable() target defined inside the
    #     if (NOT CMAKE_CROSSCOMPILING) block in td/generate/CMakeLists.txt
    #     that is depended upon by the main library's custom commands
    #     (i.e. those that write files into td/generate/auto/).
    #     Currently: tl-parser, generate_mime_types_gperf (handled above),
    #     generate_mtproto, generate_common, generate_json.
    #     Also sync the install(TARGETS ...) list in fix-cross-compile.patch
    #     and the vcpkg_copy_tools() list below.
    #
    #  4. Output directories pre-created with file(MAKE_DIRECTORY):
    #     Must cover every directory that generator executables write into.
    #     Check the WORKING_DIRECTORY and output paths of the custom commands
    #     in td/generate/CMakeLists.txt and tdutils/generate/CMakeLists.txt.
