CMAKE_前缀_路径不适用于Android

我已经从git为android编译了Qt5.15.2（仅适用于armeabi-v7a），现在我正在尝试为android编译我的Qt5应用程序。QtCreator以前编译到android的时候还不错，但因为这个原因停止了工作。所以我想从终端编译我的应用程序

以下是我的想法：-

export QT_ROOT=/path/to/QT/installation
导出此=/home/kol/untitled/build
导出ANDROID_API=21
导出工具链=$ANDROID\u NDK/toolchains/llvm/prebuild/linux-x86\u 64/bin/armv7a linux AndroidABI
导出CMAKE_前缀_路径=$QT_根/lib/CMAKE/Qt5
ls$CMAKE_前缀_路径
cmake-GNinja\
-DANDROID_SDK=$ANDROID_主页\
-DCMAKE_ANDROID_NDK=$ANDROID_NDK\
-DANDROID_NATIVE_API_LEVEL:STRING=$ANDROID_API\
-蒲公英ABI=armeabi-v7a\
-DANDROID\u STL=c++\u共享\
-DANDROID_工具链=叮当声\
-DCMAKE\u TOOLCHAIN\u文件：PATH=$ANDROID\u NDK/build/cmake/ANDROID.TOOLCHAIN.cmake\
-DCMAKE_CXX_编译器=$TOOLCHAIN$ANDROID_API-clang++\
-DCMAKE_C_编译器=$TOOLCHAIN$ANDROID_API-clang\
-DCMAKE_PREFIX_PATH=$CMAKE_PREFIX_PATH
-DCMAKE\u SYSTEM\u NAME=Android\
-DQT_QMAKE_可执行文件=$QT_ROOT/bin/QMAKE\
-DCMAKE\u BUILD\u TYPE=发布

这使我感到：-

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

ls命令清楚地显示了

Qt5Config.cmake

存在于给定的

cmake\u PREFIX\u路径中，但cmake仍然找不到它。
cmake\u PREFIX\u路径
用于安装前缀，在您的例子中是
QT\u ROOT
。注意，在交叉编译的情况下，工具链可能要求安装前缀位于sysroot之下。如果要使用
Qt5Config.cmake
文件指定目录，请设置
QT_DIR
变量，如错误消息所示，此变量不受交叉编译的影响。
