Resolves https://github.com/microsoft/vcpkg/issues/32653
The problem is that regardless of `LIBKEA_WITH_GDAL` it runs `find_package(GDAL`. (Ignoring the answer) Inside GDAL's package, they do `find_dependency(HDF5 COMPONENTS C)` which overrides kealib's attempted `find_package(HDF5 COMPONENTS CXX HL REQUIRED)` with the wrong libraries.
