Fix cmake install location

[kschwarz-intrepidcs]

CMake's find_package() will search these paths when attempting to find a package config (note that while CMake's docs appear to indicate that <name> is optional (*) it's actually required):

<prefix>/
<prefix>/(cmake|CMake)/
<prefix>/<name>*/
<prefix>/<name>*/(cmake|CMake)/
<prefix>/<name>*/(cmake|CMake)/<name>*/
<prefix>/(lib/<arch>|lib*|share)/cmake/<name>*/
<prefix>/(lib/<arch>|lib*|share)/<name>*/
<prefix>/(lib/<arch>|lib*|share)/<name>*/(cmake|CMake)/
<prefix>/<name>*/(lib/<arch>|lib*|share)/cmake/<name>*/
<prefix>/<name>*/(lib/<arch>|lib*|share)/<name>*/
<prefix>/<name>*/(lib/<arch>|lib*|share)/<name>*/(cmake|CMake)/

The current minizip-ng config install location of <prefix>/lib*/cmake/minizip-config.cmake will not be found because the config is expected to be in a minizip subdirectory under cmake.

This can be tested with:

set(CMAKE_PREFIX_PATH "/tmp/a1f568d6/install;/tmp/95d43940/install")

find_package(minizip CONFIG REQUIRED)

message("${minizip_DIR}")
