Question

我正在使用CLion构建一个FFmpeg项目，该项目使用cmake来编译代码。在开始使用libswresample库之前，一切工作都很好。由于某些原因，cmake无法看到dylib，因此无法构建代码。

Completion handler was called.

但是，如果我运行此clang代码，则可以正常编译

/Applications/CLion.app/Contents/bin/cmake/mac/bin/cmake --build /Users/user/CLionProjects/IC4D/cmake-build-debug --target all -- -j 4
[ 50%] Linking C executable IC4D

make[2]: *** [IC4D] Error 1
make[1]: *** [CMakeFiles/IC4D.dir/all] Error 2

这是我的CMakeList.txt文件：

clang -I/usr/local/include -L/usr/local/lib -lavcodec -lavcodec -lswscale -lavformat -lswresample -lSDL2 -lavutil -o IC4D2 ../main.c

我的cmake怎么了？

谢谢

与libswresample的cmake构建错误，与clang一起正常工作
