Question

CMake未能找到图书馆，我不知道为什么。这是我的CMakeLists.txt中应该找到库的部分：

set(SODIUM_DIR ${PROJECT_SOURCE_DIR}/../../../deps/install/libsodium/android-${ANDROID_ABI}/lib)
message(STATUS SODIUM_DIR=${SODIUM_DIR})
find_library(sodium-lib
             libsodium.a
             PATHS ${SODIUM_DIR}
             NO_DEFAULT_PATH)

CMake的部分输出是：

-- SODIUM_DIR=/Users/csimmons/Documents/repos/onedoclily/client/Android/app/../../../deps/install/libsodium/android-armeabi-v7a/lib
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
-- Configuring incomplete, errors occurred!
Please set them or make sure they are set and tested correctly in the CMake files:
See also "/Users/csimmons/Documents/repos/onedoclily/client/Android/app/.externalNativeBuild/cmake/debug/armeabi-v7a/CMakeFiles/CMakeOutput.log".
sodium-lib
    linked by target "native-lib" in directory /Users/csimmons/Documents/repos/onedoclily/client/Android/app
Build command failed.

在SODIUM_DIR上运行“ls”表示该库在那里：

$ ls /Users/csimmons/Documents/repos/onedoclily/client/Android/app/../../../deps/install/libsodium/android-armeabi-v7a/lib
libsodium.a libsodium.la    libsodium.so    pkgconfig

Answer 1

在可能的名称列表之前缺少标记NAMES。

修正：

find_library(sodium-lib
         NAMES libsodium.a
         PATHS ${SODIUM_DIR}
         NO_DEFAULT_PATH)

请参阅How can I find a library name of .so file?

Answer 2

我相信我已经能够通过使用add_library和set_property而不是find_library来解决问题。

set(SODIUM_PATH ${PROJECT_SOURCE_DIR}/../../../deps/install/libsodium/android-${ANDROID_ABI}/lib/libsodium.a)
add_library(sodium-lib STATIC IMPORTED)
set_property(TARGET sodium-lib PROPERTY IMPORTED_LOCATION ${SODIUM_PATH})
target_link_libraries( # My code's library.
                       native-lib
                       sodium-lib
                       )

CMake find_library无法找到库
