windows containers default to old cmake version (3.20.1)

[Terrabits]

Hi,

I am new to dockcross; I apologize in advance if I am missing something that should be obvious.

I am trying to compile a C/C++ application which requires a cmake version greater than or equal to 3.24. I tried to compile with the windows-static-x64-posix container, but it failed the cmake version check.

Investigating from bash, I get the following:

[/work] $ cmake --version
== Using MXE wrapper: /usr/src/mxe/usr/bin/x86_64-w64-mingw32.static.posix-cmake
     - cmake version 3.20.1
     - warnings for unused CMAKE_POLICY_DEFAULT variables can be ignored
== Using MXE toolchain: /usr/src/mxe/usr/x86_64-w64-mingw32.static.posix/share/cmake/mxe-conf.cmake
== Using MXE runresult: /usr/src/mxe/usr/share/cmake/modules/TryRunResults.cmake
== Adding "-DCMAKE_BUILD_TYPE=Release"
loading initial cache file /usr/src/mxe/usr/share/cmake/modules/TryRunResults.cmake
CMake Error at /usr/src/mxe/usr/share/cmake/modules/TryRunResults.cmake:1 (SET):
  Unknown CMake command "SET".


cmake version 3.20.1

CMake suite maintained and supported by Kitware (kitware.com/cmake).

Poking around the container, I also found two ccmake executables in the path. Both execute cmake version 3.24.1:

[/work] $ ccmake --version
ccmake version 3.24.2

CMake suite maintained and supported by Kitware (kitware.com/cmake).

It looks like there are two cmake versions installed, and unfortunately both cmake executables in path point to the old version.

For comparison, I ran the following in a linux-arm64 container:

[lalic:/work] $ cmake --version
cmake version 3.24.2

CMake suite maintained and supported by Kitware (kitware.com/cmake).

This is what I expected to see in the windows-* containers.

Is this a bug in the windows containers?

Note that I am using the latest dockcross commit from Github (670f7f7c5c437673acdd025d8158fc44acdb8369). Also note that I am on MacOS and using docker version `20.10.21, build baeda1f.

Thanks!
