Thanks Marius for gist, I am afraid it is unlikely to work out for me as it
still refers to QT_QMAKE_TARGET which is set to Qt6::qmake
In the cmake files ship with *Qt5* I see this (in Qt5CoreConfigExtras.cmake)
if (NOT TARGET Qt5::qmake)
add_executable(Qt5::qmake IMPORTED)
set(imported_location "${_qt5Core_install_prefix}/bin/qmake")
_qt5_Core_check_file_exists(${imported_location})
set_target_properties(Qt5::qmake PROPERTIES
IMPORTED_LOCATION ${imported_location}
)
endif()
In the cmake files ship with *Qt6* I see this
(in Qt6CoreToolsAdditionalTargetInfo.cmake)
# Default configuration
if(_qt_imported_location_default)
set_property(TARGET Qt6::qmake PROPERTY IMPORTED_LOCATION
"${_qt_imported_location_default}")
endif()
For the Qt5 cmake configuration, the setting of the path to the actual
qmake binary whereas in the Qt6 variant, is looks like a generic import
location not tied to qmake specifically. I am wondering if that is the
reason why trying to use Qt6::qmake results it not working because it was
not setup to an actual binary file location.
Cheers
