Environment variable substituion: Kit environment and buildDirectory

Brief Issue Summary

"cmake.buildDirectory" : "${env.VARNAME}" does not work if VARNAME is set in active kit’s "environmentVariables". Empty string is used instead. Ditto for "cmake.installPrefix".

Although, the following works fine:

1. "cmake.buildDirectory" : "${buildKit}"
2. "cmake.configureSettings: { "SOME_SETTING" : "${env.VARNAME}" }
3. "cmake.buildDirectory" : "${env.VARNAME}" - if VARNAME is set in environment before running vscode, instead of the kit.

Expected:

Values of variables set in active kit’s "environmentVariables" to be used in ${env.XXX} substitution for "cmake.buildDirectory" and "cmake.installPrefix".

Apparent Behavior:

1: .vscode/cmake-kits.json:

[
   {
      "name": "TEST_KIT",
      "environmentVariables": {"TEST_VAR": "TEST"}
   }
]

2: .vscode/settings.json:

   "cmake.configureSettings": {
      "TEST_SETTING": "${env.TEST_VAR}"
   },
   "cmake.buildDirectory": "${workspaceFolder}/__build/${env.TEST_VAR}-${buildKit}-${buildType}",

1. CMake: Select Kit => TEST_KIT

2. CMake: Delete Cache and Reconfigure

3. Output: CMake/Build see below

Other Notes/Information

Is it expected bahaviour, am I doing something wrong, or is it a bug?

BTW, thanks for the great extension!

CMake Tools 1.7.1 was released today and it contains a fix for this issue. Upgrade the extension in VSCode and let us know if you encounter any other problems.

I want to use this “feature” inside cmake.cmakePath in settings.json (in workspace). But it does not work. Neither with version 1.7.1 nor with the current version 1.9.1 od cmake-tools extension. The environment variable is always empty. VScode is version 1.62.2

In cmake.tools-kits.json …

{ “name”: “Ipetronik-Logger (Develop)”, “environmentVariables”: { “IpeBuildPath”: “/home/fabrice/embeddedLinux/Develop/x86_build_develop” }, “toolchainFile”: “/home/fabrice/embeddedLinux/Develop/x86_build_develop/host/usr/share/buildroot/toolchainfile.cmake” },

in settings.json …

“cmake.configureOnOpen”: true, “cmake.cmakePath”: “${env:IpeBuildPath}/host/bin/cmake”, “cmake.generator”:“Ninja”,

Result :

 Bad CMake executable "/host/bin/cmake". Is it installed or settings contain the correct path (cmake.cmakePath)?
