Description
I have a cmake project that build a library that depends on Qt Components like Qt6::WebSockets and Qt6::Mqtt .
find_package(Qt6 COMPONENTS Core OPTIONAL_COMPONENTS WebSockets Mqtt) if (Qt6_FOUND) qt_standard_project_setup() if(NOT TARGET Qt6::WebSockets) FetchContent_Declare( qtwebsockets GIT_REPOSITORY git://code.qt.io/qt/qtwebsockets.git GIT_TAG 6.5.0 ) FetchContent_MakeAvailable(qtwebsockets) endif() if(NOT TARGET Qt6::Mqtt) FetchContent_Declare( qtmqtt GIT_REPOSITORY git://code.qt.io/qt/qtmqtt.git GIT_TAG 6.5.0 ) FetchContent_MakeAvailable(qtmqtt) endif() endif(Qt6_FOUND) add_library(qclientMQTT include/client/qclientMQTT.hpp qclientMQTT.cpp src/qwebsocketiodevice.cpp include/client/qwebsocketiodevice.hpp) ...
So if it does not find the OPTIONAL_COMPONENTS WebSockets Mqtt, it will download them and built them.
The library compiles well for Windows, Macos and Linux.
I also create packages of the library by using CPack like:
cpack -B package --config CPackConfig.cmake
This works well for macos and linux returning(for linux):
CPack: Create package using STGZ CPack: Install projects CPack: - Install project: QtIotaClient [] CPack: Create package CPack: - package: /home/runner/work/_temp/build/package/QtIotaClient-v0.1.1-Linux_5.15.0-1039-azure-x86_64-GNU.sh generated. CPack: Create package using TGZ CPack: Install projects CPack: - Install project: QtIotaClient [] CPack: Create package CPack: - package: /home/runner/work/_temp/build/package/QtIotaClient-v0.1.1-Linux_5.15.0-1039-azure-x86_64-GNU.tar.gz generated. CPack: Create package using TZ CPack: Install projects CPack: - Install project: QtIotaClient [] CPack: Create package CPack: - package: /home/runner/work/_temp/build/package/QtIotaClient-v0.1.1-Linux_5.15.0-1039-azure-x86_64-GNU.tar.Z generated.
but for windows it returns:
CPack: Create package using NSIS CPack: Install projects CPack: - Install project: QtIotaClient [] CPack: - Install component: Devel CPack: - Install component: Unspecified CPack: - Install component: _install_html_docs_Mqtt CMake Error at D:/a/_temp/build/_deps/qtmqtt-build/src/mqtt/cmake_install.cmake:118 (file): file INSTALL cannot find "D:/a/_temp/build/./doc/qtmqtt": File exists. Call Stack (most recent call first): D:/a/_temp/build/_deps/qtmqtt-build/src/cmake_install.cmake:42 (include) D:/a/_temp/build/_deps/qtmqtt-build/cmake_install.cmake:42 (include) D:/a/_temp/build/cmake_install.cmake:81 (include) CPack Error: Error when generating package: QtIotaClient
So for windows it is trying to install the documentation of the COMPONENT and other things and fails. The later described behavior happens when cmake do not find the Mqtt COMPONENT and try to package the compiled COMPONENT source.
