arm-linux-gnueabihf-gcc交叉编译的时候Could NOT find Libev (missing: LIBEV_LIBRARY) (found version "4.22")

[BigHero47]

执行cmake .. && make install
结果出现
CMake Error at /usr/share/cmake-3.10/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
Could NOT find Libev (missing: LIBEV_LIBRARY) (found version "4.22")

Libev已经安装，在CMakeLists.txt里面也添加了路径，请问这个错误该如何解决

请问兄弟你解决了么？我就算在CMakeList里设置LIBEV_LIBRARY和LIBEV_INCLUDE_DIR编译都还是说找不到libev

根据/rtty-v8.1.0/CROSS_COMPILE.md说编译根本不行
这样就可以：
cmake . -DCMAKE_SYSTEM_NAME=Linux -DCMAKE_C_COMPILER=arm-linux-gnueabi-gcc -DCMAKE_FIND_ROOT_PATH="/home/xgj/workspace/V2X_4G_RSU/toolchain/arm-linux-gnueabi/bin" -DLIBEV_INCLUDE_DIR="/home/xgj/workspace/lib_3th/tmp/rtty/include" -DLIBEV_LIBRARY="/home/xgj/workspace/lib_3th/tmp/
rtty/lib/libev.so"

DESTDIR=/home/xgj/workspace/lib_3th/tmp/rtty
make install
