Copy arbitrary file out of the bin directory using the portfile? (NOT an .exe.)

[crgnam]

My package ships (optionally) with an executable that requires several SPIR-V shaders present at runtime. These are successfully built and installed to bin/shaders/.

I use vcpkg_copy_tools() to copy my executable to the tools/ directory, however I am unable to do the same with the shaders. The files in question are named viewport.frag.spv and pinhole.vert.spv. So they do not have a .exe extension, which is what vcpkg_copy_tools() appears to be looking for.

What I have attempted is adding the following to my portfile.cmake:

if("vulkan" IN_LIST FEATURES)
    vcpkg_copy_tools(
        TOOL_NAMES
            viewport.frag
            pinhole.vert
        SEARCH_DIR ${CURRENT_PACKAGES_DIR}/bin/shaders
        DESTINATION ${CURRENT_PACKAGES_DIR}/tools/${PORT}/shaders
    )
endif()

This throws the following error:

CMake Error at scripts/cmake/vcpkg_copy_tools.cmake:36 (message):
  Couldn't find tool "viewport.frag":
 
    "C:/Users/cgnam/vcpkg/packages/vira_x64-windows/bin/shaders/viewport.frag.exe" does not exist

I have also tried just putting viewport and pinhole (without the .frag/.vert), but it similarly failed.

Is there anyway to manually copy these files (or the entire shaders/ directory) into the tools/ directory?

(NOTE: This is all on a private registry, as it is not yet open-sourced):

I had a brain fart and forgot that portfile.cmake is a regular cmake file we can use cmake commands from within. Therefore the simplest solution is to just use the following:

if("vulkan" IN_LIST FEATURES)
    file(COPY ${CURRENT_PACKAGES_DIR}/bin/shaders
        DESTINATION ${CURRENT_PACKAGES_DIR}/tools/${PORT}/
    )
endif()
