Qt Quick 2 Extension Plugin compilation for android fails due qmldir not found

[Tramvon]

I have QML extention plagin created by QtCreator wizzard. When I try to compile it for android, compilation fails with message:
@mingw32-make[1]: Entering directory 'F:/work/app-project/build-app-Android_for_armeabi_GCC_4_8_Qt_5_3_1-Debug/extention'
mingw32-make[1]: *** No rule to make target 'F:\work\app-project\build-app-Android_for_armeabi_GCC_4_8_Qt_5_3_1-Debug\extention\qmldir', needed by 'libextention.so'. Stop.@

What is wrong with extention .pro file? Host OS - Windows 7, Qt - 5.3.1

@TEMPLATE = lib
TARGET = extention
QT += qml quick declarative
CONFIG += qt plugin

TARGET = $$qtLibraryTarget($$TARGET)
uri = com.example.extention

Input

SOURCES +=
Plugin.cpp
extention.cpp

HEADERS +=
Plugin.h
extention.h

OTHER_FILES = qmldir

!equals(PRO_FILE_PWD, $$OUT_PWD) {
copy_qmldir.target = $$OUT_PWD/qmldir
copy_qmldir.depends = $$PRO_FILE_PWD/qmldir
copy_qmldir.commands = $(COPY_FILE) "$$replace(copy_qmldir.depends, /, $$QMAKE_DIR_SEP)" "$$replace(copy_qmldir.target, /, $$QMAKE_DIR_SEP)"
QMAKE_EXTRA_TARGETS += copy_qmldir
PRE_TARGETDEPS += $$copy_qmldir.target
}

qmldir.files = qmldir
unix {
installPath = $$[QT_INSTALL_QML]/$$replace(uri, \., /)
qmldir.path = $$installPath
target.path = $$installPath
INSTALLS += target qmldir@
