cmake:missing and no known rule to make it when I import a prebuilt library

Question

I want to import a prebuilt library using this CmakeLists.txt snippet:

add_library(openssl-crypto
            SHARED
            IMPORTED )
set_target_proper         


        

Answer 1

You can use set_property function with attribute TARGET instead of set_target_properties, and then you can set path relatively using macros ${PROJECT_SOURCE_DIR}.

# import shared library libmylib.so    
add_library( my-imported-lib 
             SHARED 
             IMPORTED) 

# set the path to appropriate so files with appropriate architectures
set_property(TARGET 
             my-imported-lib 
             PROPERTY IMPORTED_LOCATION ${PROJECT_SOURCE_DIR}//${ANDROID_ABI}/libmy-imported-lib.so) 

...

# link imported library to your developed library
target_link_libraries( my-developed-lib 
                       my-imported-lib ) 

Maybe you can use macros ${PROJECT_SOURCE_DIR} while set lib path with set_target_properties but I didn't check this way.
