I usually install components with:  
`cmake -DCOMPONENT=componentA -P cmake_install.cmake`  
With workdir in Build dir (specified in configure call)

With presets, the Build dir is burried somewhere in the CMakePresets.json file. I do not know it without parsing the file and completing the macros:  
` "binaryDir": "${sourceDir}/Build/$env{TOOLCHAIN}-$env{BUILD_TYPE}-${generator}",`

This is a pain so I hoped, I could use `cmake --install` (introduced in 3.15) like  
`cmake --install --component componentA --preset presetA`  
but it did not work.

Is there an other way or would this be a new feature?

A workaround is:

```auto
add_custom_target(install_componentA
   # Dont use cmake --install for compatibility
   COMMAND ${CMAKE_COMMAND} cmake -DCOMPONENT=componentA -P ${CMAKE_BINARY_DIR}/cmake_install.cmake
)

```

And then use:  
`cmake --build --preset presetA --target install_componentA`

I made a proposal in [Help converting most of a CI matrix to presets?](https://discourse.cmake.org/t/help-converting-most-of-a-ci-matrix-to-presets/3391) that should help you with this… I’d appreciate in up-vote there if possible…

I’ll also add a comment linking to this one…
