I am using `cmake` to build my project in linux.

An error is reported:

```auto
build] [0%] Automatic MOC for target SUTKBaseCore
[build] [0%] Built target SUTKBaseCore_autogen
[build] [16%] Linking CXX shared library libSUTKBaseCored.so
[build] /bin/ld: /home/qiang_zhang/Desktop/Thirdparty/FMT9.1.0/install/lib/libfmt.a(format.cc.o): relocation R_X86_64_PC32 against symbol `stderr@@GLIBC_2.2.5' can not be used when making a shared object; recompile with -fPIC

```

I have tried to add `add_compile_options(-fPIC)` and `target_compile_options(SUTKBaseCore PRIVATE -fPIC)` in my `CMakeLists.txt`, but it do not work.

How can I fix this error? Any suggestion is appreciated~~~

My environment is:

```auto
linux
gcc 8.4.0 x86_64-linux-gun

```

You need to compile `fmt` with `-fPIC`. You can pass `-DCMAKE_POSITION_INDEPENDENT_CODE=ON` to `fmt` configure to make this happen.
