在Android上找不到LZ4 CMake

Question

我试图在Android中编译OpenVPN库，但我得到了以下错误：

C/C++ debug|x86 : CMake Error at /home/user/Android/Sdk/cmake/3.10.2.4988404/share/cmake-3.10/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
  Could NOT find LZ4 (missing: LZ4_LIBRARY LZ4_INCLUDE_DIR)
Call Stack (most recent call first):
  /home/user/Android/Sdk/cmake/3.10.2.4988404/share/cmake-3.10/Modules/FindPackageHandleStandardArgs.cmake:378 (_FPHSA_FAILURE_MESSAGE)
  /home/user/orwell2/deps/libopenvpn3/openvpn3/cmake/FindLZ4.cmake:5 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
  /home/user/orwell2/deps/libopenvpn3/openvpn3/cmake/findcoredeps.cmake:84 (find_package)
  /home/user/orwell2/deps/libopenvpn3/src/libopenvpn/CMakeLists.txt:24 (add_core_dependencies)
Affected Modules: app

这是FindLZ4.cmake文件：

find_path(LZ4_INCLUDE_DIR NAMES lz4.h)
find_library(LZ4_LIBRARY NAMES lz4)

include(FindPackageHandleStandardArgs)
FIND_PACKAGE_HANDLE_STANDARD_ARGS(
        LZ4 DEFAULT_MSG
        LZ4_LIBRARY LZ4_INCLUDE_DIR)

mark_as_advanced(LZ4_INCLUDE_DIR LZ4_LIBRARY)

我在我的debian10上安装了debian10。

当我在Android之外运行这个程序时：

cmake_minimum_required(VERSION 3.5)
find_library(LZ4_LIBRARY NAMES lz4)
message(STATUS, ${LZ4_LIBRARY})

我得到了liblz4文件的路径。为什么在Android上失败了？

Answer 1

解决方案是安装lz4 dev包，而不是常规的包，下面是命令：

sudo apt install -y liblz4-dev

希望这能有所帮助！
