我正在尝试为使用 Boost 库的代码创建一个 CMake 项目。我想为 Android 构建它,我使用这个项目作为参考:https ://code.google.com/p/android-cmake/ 。
我想使用我之前为 android 构建的 Boost 静态库,而不是让它们成为要编译的项目的一部分。
这是我使用 Boost 的项目部分的 CMakeLists.txt
#BOOST
set(BOOST_ROOT /home/neb/workspace/SDLActivityCMAKE/jni/boost)
set(Boost_INCLUDE_DIR /home/neb/workspace/SDLActivityCMAKE/jni/boost/include/boost-1_53)
set(BOOST_INCLUDEDIR /home/neb/workspace/SDLActivityCMAKE/jni/boost/include/boost-1_53)
set(Boost_LIBRARY_DIR /home/neb/workspace/SDLActivityCMAKE/jni/boost/lib)
set(BOOST_LIBRARYDIR /home/neb/workspace/SDLActivityCMAKE/jni/boost/lib)
set(Boost_USE_STATIC_LIBS ON)
set(USE_STATIC_BOOST ON)
set(Boost_USE_STATIC_RUNTIME ON)
set(BOOST_COMPILER gcc)
find_package(Boost COMPONENTS "thread-gcc-mt-1_53" "date_time-gcc-mt-1_53" REQUIRED)
include_directories(${Boost_INCLUDE_DIR})
link_directories(${Boost_LIBRARY_DIR})
#BOOSTEND
add_executable(main main.cpp)
target_link_libraries( main ${Boost_LIBRARIES} )
当我运行常规cmake
命令(cmake ..
来自android项目中jni文件夹的子目录)没有问题时,cmake会找到库。当我让 cmake 使用上述项目提供的 android.toolchain.cmake 时,我得到了这个(我正在使用 -DBoost_DEBUG 选项)。

所以我看到 CMake 正在这个确切的目录中搜索库:
/home/neb/workspace/SDLActivityCMAKE/jni/boost/lib
其中有编译的静态库:

我设置了指向我能找到的 BOOST 目录的所有变量,我设置了变量说 Boost 库应该是静态的,但它仍然找不到它们。我还可以做些什么?
