The `antlr4-runtime` CMake package provided by `antlr4-cpp-runtime-devel` seems to require both `/usr/lib64/libantlr4-runtime.so` and `/usr/lib64/libantlr4-runtime.a` to function properly, since it has two targets (`antlr4_shared` and `antlr4_static`) and will check if both are configured properly. However the static library is missing in the package.

Error message:

```
CMake Error at /usr/lib64/cmake/antlr4-runtime/antlr4-targets.cmake:85 (message):
  The imported target "antlr4_static" references the file

     "/usr/lib64/libantlr4-runtime.a"

  but this file does not exist.  Possible reasons include:

  * The file was deleted, renamed, or moved to another location.

  * An install or uninstall procedure did not complete successfully.

  * The installation package was faulty and contained

     "/usr/lib64/cmake/antlr4-runtime/antlr4-targets.cmake"

  but not all the files it references.

Call Stack (most recent call first):
  /usr/lib64/cmake/antlr4-runtime/antlr4-runtime-config.cmake:42 (include)
  CMakeLists.txt:57 (find_package)
```

Reproducible: Always

Steps to Reproduce:
1. Create a new CMake project
2. Add `find_package(antlr4-runtime REQUIRED)` to the `CMakeLists.txt`
3. Run `cmake .`
Actual Results:

Expected Results:  
Load the CMake package normally without errors.
