I'm sorry but i don't understand how to use ndk-pkg installed packages in cmake projects. And yes, i have read documentation hundred times, moreover i have read instructions shown in terminal on ndk-pkg deploy. I added all suggested to build.gradle, i added all suggested to CMakeLists.txt but building says:

CMake Error at CMakeLists.txt:188 (find_package): Could not find a package configuration file provided by "somelib" with any of the following names:

somelibConfig.cmake somelib-config.cmake

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

What do i do wrong?

could you show me :

the ndk-pkg commands you run
your build.gradle
your CMakeLists.txt

Qt for iOS sets MACOSX_BUNDLE_GUI_IDENTIFIER automatically since Qt 6.1.

If you are developing for iOS or macOS you should consider setting an

explicit, fixed bundle identifier manually though.

libssh's dependencies are also should be deploied by yourself.

./ndk-pkg deploy android-34-arm64-v8a/openssl-dev
./ndk-pkg deploy android-34-arm64-v8a/libz
./ndk-pkg deploy android-34-arm64-v8a/libssh

i just tried link openssl-dev and it have same error:

CMake Error at CMakeLists.txt:192 (find_package):
  Could not find a package configuration file provided by "openssl-dev" with
  any of the following names:

    openssl-devConfig.cmake
    openssl-dev-config.cmake

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

Could you explain how cmake should find package if there is no any path to ndp-pkg or maven repository in CMakeLists.txt?

eSKond commented 1 day ago

btw i can link all libraries with something like:

set(NDK_PKG_HOME_DIR /Users/sergey/.ndk-pkg)
add_library(
        libssh
        STATIC
        IMPORTED
)
set_target_properties(
        libssh
        PROPERTIES IMPORTED_LOCATION
        ${NDK_PKG_HOME_DIR}/installed/android-34-arm64-v8a/libssh/lib/libssh.a
)

but perhaps it's not expected way of using ndk-pkg, right?
