### Bug description

When trying to find_package PcapPlusPlus installed with vcpkg, it fails with the following:

```

CMake Error at build/vcpkg_installed/x64-linux/share/pcapplusplus/FindPCAP.cmake:113 (try_run):

  Unknown extension ".c" for file



    .../build/detect_pcap_version.c



  try_compile() works only for enabled languages.  Currently these are:



    CUDA CXX



  See project() command to enable other languages.

```



My project indeed only enable those two languages and not C.

It used to work but block my upgrade to PcapPlusPlus 24.09.



I think `detect_pcap_version.c` (introduced in 71e19fe1fbd2cc05094a152679ba4e4aa39b0aa9) should be a C++ file so it doesn't require C to be enabled.
