我可以从 git 下载 Qt 源并将其签出到 5.15.2 并为 android 编译它。我已经在 Qt Creator 中创建了它的工具包，它成功地构建了我的应用程序。但是我怎么能在没有 qt creator 的终端中做到这一点

我试过以下： -

export QT_ROOT=/home/noone/Development/KDE/Qt/build/installation

cmake .. -GNinja \
    -DCMAKE_BUILD_TYPE:String=Release \
    -DQT_QMAKE_EXECUTABLE:STRING=$QT_ROOT/bin/qmake \
    -DCMAKE_PREFIX_PATH:STRING=/home/noone/untitled1/build/installation \
    -DCMAKE_C_COMPILER:STRING=$ANDROID_NDK/toolchains/llvm/prebuilt/linux-x86_64/bin/clang \
    -DCMAKE_CXX_COMPILER:STRING=$ANDROID_NDK/toolchains/llvm/prebuilt/linux-x86_64/bin/clang++ \
    -DANDROID_NATIVE_API_LEVEL:STRING=16 \
    -DANDROID_NDK:PATH=$ANDROID_NDK \
    -DCMAKE_TOOLCHAIN_FILE:PATH=$ANDROID_NDK/build/cmake/android.toolchain.cmake \
    -DANDROID_ABI:STRING=armeabi-v7a \
    -DANDROID_SDK:PATH=$ANDROID_HOME \
    -DANDROID_STL:STRING=c++_shared \
    -DCMAKE_FIND_ROOT_PATH:PATH=$QT_ROOT

但它给出了以下错误： -

-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Check for working CXX compiler: /optHDD/AndroidNDK/toolchains/llvm/prebuilt/linux-x86_64/bin/clang++ - skipped

CMake Error at CMakeLists.txt:16 (find_package):
  Could not find a package configuration file provided by "ECM" (requested
  version 5.74) with any of the following names:

    ECMConfig.cmake
    ecm-config.cmake

  Add the installation prefix of "ECM" to CMAKE_PREFIX_PATH or set "ECM_DIR"
  to a directory containing one of the above files.  If "ECM" provides a
  separate development package or SDK, be sure it has been installed.
