Android，CMake和静态链接

标签： android-ndk cmake

在Google hello-libs example之后将库项目构建从Android.mk转换为CMakeLists.txt，我遇到了避免未定义引用的问题。我正在使用一个名为DCMTK的开源项目，并将DCMTK和ICONV编译为我随后链接的静态库。使用Android.mk进行构建可以通过ndk-build进行构建并构建它们当我将每个静态库添加到gradle时，使用CMakeLists.txt和以下target_link_libraries。但是，我想使用add_library来完成这项工作并尝试

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 )

为每个库，然后将它们添加到target_link_libraries。这导致了大量未定义的引用。我还尝试通过将静态库分组到一个目标中来设置set_target_properties，但这也不起作用。

依赖关系的顺序是否以某种方式不同或者CMake使用add_library set_target_properties方法处理这些库的方式不同？

虽然我不确定添加所有静态库的IMPORTED_LOCATION，但是将工作依赖顺序分解为库确实有效。
