[Bug] condition in inherited build preset passes, but inherited build presets are not listed for selection

[david-fong]

Brief Issue Summary

I'm using CMake v4.0. I can repro with my emscripten presets in https://github.com/david-fong/okiidoku/commit/399fcdb94525e690f35baaf270ae670ef3985529. I can't work up the motivation to make a minimal repro right now- apologies. Relevant snippets from my preset file:

		{
			"name": "tool:emscripten",
			"hidden": true,
			"description": "available if you set/export EMSDK environment variable. good for IDEs which are hard to configure to use `emcmake cmake`.",
			"condition": {"type": "notEquals", "lhs": "$env{EMSDK}", "rhs": ""},
			"toolchainFile": "$env{EMSDK}/upstream/emscripten/cmake/Modules/Platform/Emscripten.cmake",
			"cacheVariables": {
				"CMAKE_CONFIGURATION_TYPES": "MinSizeRel;Debug;Release",
				"OKIIDOKU_BUILD_BINDINGS_FOR_PYTHON": null
			}
		},
//...
		{
			"name": "base:dev.emscripten",
			"hidden": true,
			"condition": {"type": "notEquals", "lhs": "$env{EMSDK}", "rhs": ""},
			"targets": ["all"]
		},
		{
			"name": "dev.emscripten.debug",
			"configurePreset": "dev.emscripten",
			"displayName": "debug",
			"inherits": ["base:dev.emscripten"],
			"configuration": "Debug"
		},

cmake --build --list-presets works as expected though.

It says it found 4, but only shows "\[Default\]" and "Add new preset".

Additional Information

I'm surprised CMake's file api doesn't seem to have much to support tools in implementing preset support.

Hi @david-fong, thanks for reporting issue here!

I have created a minimal repro project and reproduced issue on CMake Tools latest v1.21.8(pre-release), it only shows "[Default]" and "Add new preset" when I select Build preset, but the build preset list when running cmake --build --list-presets in terminal.

demo_project.zip

@gcampbell-msft FYI.

[gcampbell-msft]

I've reproduced and marked it as a bug to fix for the next release. Thanks

[Amy-Li03]

Verified this on CMake Tools v1.21.23(pre-release), issue was fixed. Now the inherited build presets are listed for selection.

[david-fong]

Now it doesn't even list my conditional configure preset for selection... v1.22.9

@david-fong Thank you for reporting this issue. We have verified this issue using this sample project(demo_project.zip) in VS Code 1.104.1 + CMake tools 1.22.9 and we can reproduce it. So we reopen this issue. Thank you.

I didn’t mean to send the above message :P I think the issue I was having a few days ago was related to VS Code’s shell startup file behaviour(?). I’m honestly not sure. But if you can reproduce the issue then maybe it’s still a CMake Tools bug.

@david-fong Thank you for your information. Please continue to follow up on this issue. Thank you.
