Fix compatibility with CMake 3.29.1

[traversaro]

See:

• [vcpkg-cmake-config] Wrong *Config.cmake files for CMake 3.29.1 microsoft/vcpkg#37968

• robotology-vcpkg-ports/yarp/portfile.cmake

  Line 105 in efd9179

  string(REPLACE "\${PACKAGE_PREFIX_DIR}/lib/cmake" "\${PACKAGE_PREFIX_DIR}/share" contents "${contents}")

• [vcpkg-cmake-config] Adapt get_filename_component package prefix for CMake 3.29.1 microsoft/vcpkg#38017

Note that the possibility of this kind of regression was discussed in microsoft/vcpkg#77, but it was preferred to have a uniform set of directories where to install cmake config files.

The problem was solved in CMake itself.
