configure vscode to include CMakeLists.txt file of multiple sub-project

I would like to configure correctly project's settings.json file to use CMakeLists.txt file of multiple sub-project.

My approach is given below

The structure of the project is as like as follows.

vscode_build_cmake/
`-- task
    |-- add
    |   |-- CMakeLists.txt
    |   |-- include
    |   |   `-- foo.h
    |   `-- src
    |       |-- foo.cpp
    |       `-- main.cpp
    `-- print
        |-- CMakeLists.txt
        |-- include
        |   `-- foo.h
        `-- src
            |-- foo.cpp
            `-- main.cpp

Here, add & print are completely isolated sub-project of the main project task. Each sub-project has their own build recipe which is written in their own CMakeLists.txt file. Usual steps to build sub-project is :

cd task/add
mkdir build
cd build
cmake .. && make

Same steps is for task/print.

Right now I would like to perform this build task using VSCode Cmake tool. What I have found that I only need to make a vscode_build_cmake/.vscode/settings.json file where I can point to the directory of CMakeLists.txt file. I am now working with

{
    "cmake.configureOnOpen": false,
    "cmake.sourceDirectory": "${workspaceFolder}/task/add"
}

I just press ctrl+shift+p and write in the command box run build task and press Enter. That one do the job for me and I can see build, bin, lib directories inside task/add directory.

But the problem, I am facing now is that if I need to build print sub-project I have to manually edit the settings.json file as like as follows

{
    "cmake.configureOnOpen": false,
    "cmake.sourceDirectory": "${workspaceFolder}/task/print"
}

After that, I have to delete cache and reconfigure and build task which perform now the build task only for print project. This one is very tedious to me.

My desire is to know

{
    "cmake.configureOnOpen": false,
    "cmake.sourceDirectory": ["${workspaceFolder}/task/add",
                              "${workspaceFolder}/task/print"]
}

Or ,

I am using CMake Tools v1.13.4.

CMake Tools supports an array of directories in cmake.sourceDirectory since version 1.13.40. See PR #1374.

Older answer

If you're intent on not having a tasks/CMakeLists.txt that add_subdirectorys add/ and print/, then you can consider using VS Code's multi-root workspace feature, which the vscode-cmake-tools extension supports.

If you have a reason not to use / that you don't like the multi-root workspace approach, you can show your support for vscode-cmake-tools issue #1374 ("Support Multiple CMakeLists.txt without Requiring a Multi-Root Workspace") and the proposed solutions. At the time of this writing, the proposal process is still in earlier stages.
