[windows] Missing CMake error when static QHull is not present under Windows 10 (with vcpkg)

Compuiling PCL

• under Windows 10 with vcpkg
• all the options enabled including tests
• PCL_BUILD_WITH_QHULL_DYNAMIC_LINKING_WIN32 is OFF and QHull static is not present in the system

CMake did not errored about missing library and building PCL I get this error (both in Release and Debug build):

Compiling with PCL_BUILD_WITH_QHULL_DYNAMIC_LINKING_WIN32=ON insead everything works smoothly.

I will investigate what happens when PCL_BUILD_WITH_QHULL_DYNAMIC_LINKING_WIN32=OFF in this settings.

Reproduce the Windows 10/vcpkg configuration with tests enabled and PCL_BUILD_WITH_QHULL_DYNAMIC_LINKING_WIN32 set to OFF, then inspect the CMake configuration and pcl_surface link setup. Confirm that a missing static QHull library is detected during configuration rather than only producing the qh_qh linker failure; compare with the working dynamic-linking setting.
