Fix CMake warning

The warnings occurs at least with CMake version 3.24. It is caused by
CMake trying to find the gcc library due to case sensitivity.

The warning message was:
```
CMake Warning (dev) at /usr/share/cmake-3.24/Modules/FindPackageHandleStandardArgs.cmake:438 (message):
  The package name passed to `find_package_handle_standard_args` (LIBGCC)
  does not match the name of the calling package (LibGCC).  This can lead to
  problems in calling code that expects `find_package` result variables
  (e.g., `_FOUND`) to follow a certain pattern.
Call Stack (most recent call first):
  build/cmake/FindLibGCC.cmake:17 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
  CMakeLists.txt:1269 (FIND_PACKAGE)
This warning is for project developers.  Use -Wno-dev to suppress it.
