QHotkey as CMAKE external project

[raffmont]

Dears,

I want to use QHotkey as a cmake external project within https://github.com/openfairwind/fairwindsk, in my main CMakeLists.txt I added:

ExternalProject_Add(qhotkey
GIT_REPOSITORY https://github.com/Skycoder42/QHotkey.git
CMAKE_ARGS -DCMAKE_INSTALL_PREFIX=${EXTERNAL_INSTALL_LOCATION} -DQT_DEFAULT_MAJOR_VERSION=6
TIMEOUT 360
)
set(LIBQHOTKEY ${EXTERNAL_INSTALL_LOCATION}/lib/libqhotkey.a)

...

add_dependencies(${PROJECT_NAME} qhotkey)

...

target_link_libraries(${PROJECT_NAME}
Qt::Core
Qt::Gui
Qt::Widgets
Qt::Network
Qt::WebSockets
Qt::Xml
Qt::Positioning
Qt::WebEngineWidgets
Qt::VirtualKeyboard
...
${LIBQHOTKEY}
)

I'm using an arm64 platform (MacOS 15.2; the QHotkeyTest is compiled correctly and works flawlessly).

But, when I build my project, I receive this message:

Undefined symbols for architecture arm64:

The symbols are present in libqhotkey.a

Any suggestions?
Best regards,

Solved,
Using -DBUILD_SHARED_LIBS=ON, the library is built as a dynamic library and works.
