Description
Qt6Core_INCLUDE_DIRS contains actually this on Windows
C:/Qt/6.6.0/msvc2019_64/include/QtCoreC:/Qt/6.6.0/msvc2019_64/includeC:/Qt/6.6.0/msvc2019_64/include/QtZlib$<$<BOOL:$<TARGET_PROPERTY:Qt6::ZlibPrivate,_qt_module_has_private_headers>>:>$<$<BOOL:$<TARGET_PROPERTY:Qt6::ZlibPrivate,_qt_module_has_private_headers>>:C:/Qt/6.6.0/msvc2019_64/include/QtZlib/6.6.0>$<$<BOOL:$<TARGET_PROPERTY:Qt6::ZlibPrivate,_qt_module_has_private_headers>>:C:/Qt/6.6.0/msvc2019_64/include/QtZlib/6.6.0/QtZlib>
while on Linux it only contains
/usr/include/x86_64-linux-gnu/qt6/QtCore;/usr/include/x86_64-linux-gnu/qt6
this makes cross platform development impossible. When I use this in my project:
set(CMAKE_REQUIRED_INCLUDES ${Qt6Core_INCLUDE_DIRS})
check_include_file_cxx(QtGui/qtgui-config.h HAVE_QTGUI_CONFIG_H)
it works on Linux but fails on Windows with this error
