Android, CMake and Static Linking

问题


In converting a library project build from Android.mk to CMakeLists.txt following the Google hello-libs example and I have encountered problems avoiding undefined references. I'm using an open source project called DCMTK and compiling DCMTK and ICONV to static libraries that I then link in. Building using the Android.mk works via ndk-build and building them with gradle and the following CMakeLists.txt works when I add each static library to the target_link_libraries. However, I wanted to use add_library to do the job and tried

add_library( lib_dcmdata STATIC IMPORTED )
set_target_properties( lib_dcmdata
                           PROPERTIES
                           IMPORTED_LOCATION ${CMAKE_SOURCE_DIR}/prebuilt_libs/dcmtk/${ANDROID_ABI}/lib/libdcmdata.a )

for each library and then adding them to target_link_libraries. This resulted in a ton of undefined references. I also tried set_target_properties by grouping the static libraries into one target, but this didn't work either.

Is the order of dependency linking different in some way or the way CMake handles these libraries different using the add_library set_target_properties method?

While I'm unsure about adding the IMPORTED_LOCATION of all the static libraries en masse breaking the work dependency order into libraries does work.
