Execute cmake in docker fails

[nrlmol2018]

Hi, I wanted to create a small wrapper-script to let CMakeBuilder execute "cmake ..." inside a docker container. Assuming I have a running container "ContainerName" I created a small script "cmakewrap.sh":

#!/bin/bash
docker exec -t -w /path/in/container ContainerName /usr/bin/cmake "$@"

I put this into ~/bin/ and did set "cmake_binary" to be

{
"cmake_binary": "/Users/mausername/bin/cmakewrap.sh"
}

in the setting.

(Calling cmakewrap.sh from command line works fine, e.g:

cmakewrap.sh -E capabilities
{"fileApi":{"requests":[{"kind":"codemodel","version":[{"major":2,"minor":3}]},{"kind":"cache","version":[{"major":2,"minor":0}]},{"kind":"cmakeFiles","version":[{"major":1,"minor":0}]},{"kind":"toolchains","version":[{"major":1,"minor":0}]}]},"generators":[{"extraGenerators":[],"name":"Watcom WMake","platformSupport":false,"toolsetSupport":false},{"extraGenerators":[],"name":"Ninja Multi-Config","platformSupport":false,"toolsetSupport":false},{"extraGenerators":["CodeBlocks","CodeLite","Eclipse CDT4","Kate","Sublime Text 2"],"name":"Ninja","platformSupport":false,"toolsetSupport":false},{"extraGenerators":["CodeBlocks","CodeLite","Eclipse CDT4","Kate","Sublime Text 2"],"name":"Unix Makefiles","platformSupport":false,"toolsetSupport":false},{"extraGenerators":[],"name":"Green Hills MULTI","platformSupport":true,"toolsetSupport":true}],"serverMode":false,"version":{"isDirty":false,"major":3,"minor":22,"patch":3,"string":"3.22.3","suffix":""}}
)

However, CMakeBuilder throws an error:

'There was an error loading cmake's capabilities. Your "cmake_binary" setting is set to ..."

Anyone has an idea what is going wrong here ?

BTW: is there a way to debug, I would look into it myself, however I have no idea where ST (on Mac) stores the actual (Python-)Code for the plugin ...

Best,
Torsten.
