私は CMake を初めて使用し、それを使用して小さな KDE アプリケーションを構築しようとしています。QTXml モジュールを使用する必要があり、プログラムは問題なくコンパイルされますが、リンク段階で ld は QXml コンポーネントを見つけることができません...
main.cpp
#include "test.h"
int main(int argc, char **argv)
{
return 0;
}
test.h
#ifndef TEST_H
#define TEST_H
#include <QXmlResultItems>
#include <QString>
#include <QBuffer>
#include <QXmlQuery>
class test {
public:
test(){}
~test(){}
QXmlResultItems* find ( const QString& node, const QString& xpath );
private:
QBuffer device_;
};
#endif // TEST_H
test.cpp
#include "test.h"
QXmlResultItems* test::find ( const QString& node, const QString& xpath )
{
QXmlResultItems* result = new QXmlResultItems;
QXmlQuery query;
query.bindVariable ( "device",&device_ );
query.setQuery ( "doc($device)/"+node+"/"+xpath );
query.evaluateTo ( result );
return result;
}
CMakeLists.cmake
project(qtcmakepb)
find_package(KDE4 REQUIRED)
include (KDE4Defaults)
include_directories( ${KDE4_INCLUDES} ${QT_INCLUDES} )
#Supposed to be useless because of KDE4 REQUIRED and ${QT_INCLUDES}
find_package(Qt4 COMPONENTS QtCore QtXml REQUIRED )
# In this CMakeLists.txt we define which files
# are used to compile the application
set(qtcmakepb_SRCS main.cpp test.cpp)
# Set the name of the application
kde4_add_executable(qtcmakepb ${qtcmakepb_SRCS})
# Select which libraries we need to link to
target_link_libraries(qtcmakepb ${KDE4_KDEUI_LIBS})
target_link_libraries(qtcmakepb ${QT_QTCORE_LIBS})
target_link_libraries(qtcmakepb ${QT_QTXML_LIBS})
# Tell cmake to install the application binary
install(TARGETS qtcmakepb ${INSTALL_TARGETS_DEFAULT_ARGS})
# Install the .desktop file
install( PROGRAMS qtcmakepb.desktop DESTINATION ${XDG_APPS_INSTALL_DIR} )
make の出力:

私は何を間違っていますか?
