This easaly reproduced runing the cmake command
cmake ../../maplibre-native-qt -G "Ninja Multi-Config"
-DCMAKE_CONFIGURATION_TYPES="Release;Debug"
-DCMAKE_C_COMPILER_LAUNCHER="ccache"
-DCMAKE_CXX_COMPILER_LAUNCHER="ccache"
-DCMAKE_DEFAULT_CONFIGS="all"
-DCMAKE_INSTALL_PREFIX="../install"
-DCMAKE_OSX_ARCHITECTURES="arm64;x86_64"
-DCMAKE_OSX_DEPLOYMENT_TARGET="14.0" -DCMAKE_PREFIX_PATH=~/Qt/6.8.1/ios --debug-find-pkg=Qt6Gui

CMake Error at CMakeLists.txt:59 (find_package):
Found package configuration file:

/Users/jcarreira/Qt/6.8.1/ios/lib/cmake/Qt6/Qt6Config.cmake

but it set Qt6_FOUND to FALSE so package "Qt6" is considered to be NOT
FOUND. Reason given by package:

Failed to find required Qt component "Gui".

Expected Config file at
"/Users/jcarreira/Qt/6.8.1/ios/lib/cmake/Qt6Gui/Qt6GuiConfig.cmake" exists

Configuring with --debug-find-pkg=Qt6Gui might reveal details why the
package was not found.
