This makes sure the internal versions of these libraries bundled with
the GZDoom source code is used. This prevents the system from building
GZDoom for dynamic linking with incompatible external libraries (see
<https://forum.zdoom.org/viewtopic.php?f=2&t=64633>).
Introduce the variable 'ZD_CMAKE_COMPILER_IS_GNUC(XX)_COMPATIBLE' and replace any occurrence of '"${CMAKE_C(XX)_COMPILER_ID}" STREQUAL "GNU" OR "${CMAKE_C(XX)_COMPILER_ID}" STREQUAL "Clang"' with it. This makes it possible to add more GCC compatible compilers in just one place.
- Added more output to zipdir and a -q option to turn it off.
- Added -u option to zipdir to only recompress those files in a zip that have
changed.
- Added -d and -f options to zipdir. -d forces deflate compression, and -f
forces a write of the zip, even if it's newer than all the files it contains.
- Added support for bzip2 and LZMA compression to zipdir.
