Build Qt Based Prjoect Qxmpp for Android 35

fep29

Any hints on building Qxmpp project (Qt Core based) for Android 35?

Reading around on the problem I found an old build script here:

https://invent.kde.org/network/kaidan/-/blob/5f9abb28050c4b5f8cf135166b156bb1cdb7cffd/utils/build-android.sh#L136

Using that, I cobbled this together:

cmake .. \
    -DCMAKE_TOOLCHAIN_FILE="$HOME/Library/Android/sdk/ndk/29.0.13113456/build/cmake/android.toolchain.cmake" \
    -DECM_ADDITIONAL_FIND_ROOT_PATH="$HOME/QtAndroid/6.8.2/android_arm64_v8a" \
    -DANDROID_NDK="$HOME/Library/Android/sdk/ndk/29.0.13113456" \
    -DANDROID_SDK_ROOT="$HOME/Library/Android/sdk" \
    -DANDROID_SDK_BUILD_TOOLS_REVISION=35.0.0 \
    -DANDROID_PLATFORM=android-35 \
    -DCMAKE_PREFIX_PATH="$HOME/QtAndroid/6.8.2/android_arm64_v8a" \
    -DBUILD_EXAMPLES=OFF \
    -DBUILD_TESTS=OFF

But getting this error:

CMake Error at CMakeLists.txt:22 (find_package):
  Could not find a package configuration file provided by "QT" with any of
  the following names:

    Qt6Config.cmake
    qt6-config.cmake
    Qt5Config.cmake
    qt5-config.cmake

  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.

Though I clearly see Qt6Config.cmake:

my-MBP Qt6 % pwd             
/path/to/QtAndroid/6.8.2/android_arm64_v8a/lib/cmake/Qt6
my-MBP Qt6 % cat Qt6Config.cmake

I have also tried modifying the CMAKE_PREFIX_PATH to: lib/cmake/Qt6 and everything in between.

Hints?

One viable option is to use Craft automated build tool.

As Linus pointed out. Tried it out. Seems to have worked.
