[CMake] QT_QTDECLARATIVE_FOUND issue on N9(50)

[Laszlo Papp]

Hi,

I made some experiment with this issue and I tried two ideas out:

1) I made a cmake_test project folder with two subfolders: foo and
bar. From the main CMakeLists.txt:
add_subdirectory(foo)
add_subdirectory(bar)

Then:
cat ../foo/CMakeLists.txt
find_package(Qt4)
if(QT_QTDECLARATIVE_FOUND)
  message("found it")
endif()

cat ../bar/CMakeLists.txt
find_package(Qt4)
if(QT_QTDECLARATIVE_FOUND)
  message("found it again")
endif()

The result was that I got both messages. It might well mean that
something is messed in my project build environment, but this is
something which I would like to ask for help with from you.

2) If I try to find the Qt4 package twice the FOUND variable is set
properly. It might help with troubleshooting the issue, but I do not
know the internal cmake operation.

find_package(Qt4)
find_package(Qt4)
    message(STATUS "QT_QTDECLARATIVE_FOUND: ${QT_QTDECLARATIVE_FOUND}")
    if(QT_QTDECLARATIVE_FOUND)
        add_subdirectory(touch)
    else(QT_QTDECLARATIVE_FOUND)
        message(WARNING "Qt installation lacks Qt Declarative -
disabling touch based player")
    endif(QT_QTDECLARATIVE_FOUND)
