The media-autobuild suite recently added experimental support for ccache
(provided by MSYS2 as mingw-w64-x86[_64]-ccache 3.7.2-1).
The configuration step for x265 seems to fail requesting its feature set
correctly, I even doubt it is aware of its presence at all, and its
hooking into compiler calls might have unwanted side effects.
An example from the configuration in an MSYS2-64/MinGW32 compilation:
+----
-- cmake version 3.15.2
CMake Deprecation Warning at CMakeLists.txt:10 (cmake_policy):
The OLD behavior for policy CMP0025 will be removed from a future version
of CMake.
The cmake-policies(7) manual explains that the OLD behaviors of all
policies are deprecated and that a policy should be set to OLD only under
specific short-term circumstances. Projects should be ported to the NEW
behavior and not rely on setting a policy to OLD.
CMake Deprecation Warning at CMakeLists.txt:16 (cmake_policy):
The OLD behavior for policy CMP0054 will be removed from a future version
of CMake.
The cmake-policies(7) manual explains that the OLD behaviors of all
policies are deprecated and that a policy should be set to OLD only under
specific short-term circumstances. Projects should be ported to the NEW
behavior and not rely on setting a policy to OLD.

E:/MABS/msys64/mingw32/bin/ccache.exe: unknown option -- d
Usage:
ccache [options]
ccache compiler [compiler options]
compiler [compiler options] (via symbolic link)
Common options:
-c, --cleanup delete old files and recalculate size
counters
(normally not needed as this is done
automatically)
-C, --clear clear the cache completely (except
configuration)
-F, --max-files=N set maximum number of files in cache to N
(use 0
for no limit)
-M, --max-size=SIZE set maximum size of cache to SIZE (use 0
for no
limit); available suffixes: k, M, G, T
(decimal)
and Ki, Mi, Gi, Ti (binary); default
suffix: G
-p, --show-config show current configuration options in
human-readable format
-s, --show-stats show summary of configuration and statistics
counters in human-readable format
-z, --zero-stats zero statistics counters
-h, --help print this help text
-V, --version print version and copyright information
Options for scripting or debugging:
--dump-manifest=PATH dump manifest file at PATH in text format
-k, --get-config=K print the value of configuration key K
--hash-file=PATH print the hash (<MD4>-<size>) of the file
at PATH
--print-stats print statistics counter IDs and
corresponding
values in machine-parsable format
-o, --set-config=K=V set configuration item K to value V
