[gdal-dev] link error with MrSID and ECW

[Kai Pastor, DG0YT]

I didn't pay much attention to the CMake code. Now:

You don't need to deal with string(CONCAT ...). Normally you just need to
- treat VCPKG_<LANG>_FLAGS as CMake string (because this follows 
CMAKE_<LANG>_FLAGS),
- treat as VCPKG_CMAKE_CONFIGURE_OPTIONS as CMake list, *quoting whole 
list items* if needed.

i.e.
list(APPEND VCPKG_CMAKE_CONFIGURE_OPTIONS
"-DMRSID_INCLUDE_DIR=${CMAKE_CURRENT_LIST_DIR}/../sdk/MrSID_DSDK-9.5.5.5244-win32-vc17/Raster_DSDK/include"
     
"-DMRSID_LIBRARY=${CMAKE_CURRENT_LIST_DIR}/../sdk/MrSID_DSDK-9.5.5.5244-win32-vc17/Raster_DSDK/lib/lti_dsdk.lib"
     ...
)
