How to check the VCPKG_LIBRARY_LINKAGE of the port in project cmake file?

Many ports provide different packages depending on whether they are dynamically or statically linked, which results in triplet-related project cmake files. This obviously doesn't make sense. So I want to be able to determine the linkage of the port in the project cmake file to import different packages. how can I do that?

Generally not possible. As a consumer, you search for packages, not static or dynamic libraries. What's your specific use case?

I only depend on a couple of libraries right now and 2 of them already have this problem. One is libdatachannel, which is dynamically linked by default for windows, so on my windows computer my cmake file has to say this:

target_link_libraries(main PRIVATE LibDataChannel::LibDataChannel)

while the linux defaults to static linking, so when my project is compiled on linux it must be written like this:

target_link_libraries(test1 PRIVATE LibDataChannel::LibDataChannelStatic)

The other one is gstreamer. for static linking I can import gstreamer-full-1.0, while for dynamic linking there is no such import item. Am I the only one experiencing this problem?

You can check if a target exists and link it accordingly:
$<TARGET_NAME_IF_EXISTS:tgt> or and if(TARGET <targetname>)

Cf. zstd:

    target_link_libraries(main PRIVATE $<IF:$<TARGET_EXISTS:zstd::libzstd_shared>,zstd::libzstd_shared,zstd::libzstd_static>)
