---@class CMakeConfig
---@field cmake CMakeConfigCMake Configuration for `cmake` command itself
---@field save_before_build boolean Save all unsaved files before running `cmake`
---@field generate_after_save boolean Generate after saving `CMakeLists.txt` file
---@field cmake_terminal CMakeConfigCMakeTerminal Settings for terminal where cmake will be executed
---@field target_terminal CMakeConfigTargetTerminal Settings for terminal where executable targets will be executed
---@field variants {[string]:CMakeVariant} Default variants. Parameters defined in variants have more priority than defined in `cmake = {...}` ones

---@class CMakeConfigCMake
---@field cmake_path string Path to `cmake` executable
---@field ctest_path string Path to `ctest` executable
---@field cpack_path string Path to `cpack` executable
---@field build_args string[] An array of additional arguments to pass to `cmake --build`
---@field build_tool_args string[] An array of additional arguments to pass to the underlying build tool
---@field generator? string Set to a string to override CMake Tools’ preferred generator logic. If this is set, CMake will unconditionally use it as the -G CMake generator command line argument
---@field parallel_jobs? number By specifying a number, you can define how many jobs are run in parallel during the build

---@class CMakeVariant
---@field default string Default choice
---@field description string Description for variant option
---@field choices {[string]:CMakeVariantChoice} Choices for variant option

---@class CMakeVariantChoice
---@field short string Short description for choice
---@field long? string Short description for choice
---@field buildType? string Value for `CMAKE_BUILD_TYPE` variable.
---@field generator? string Set to a string to override CMake Tools’ preferred generator logic. If this is set, CMake will unconditionally use it as the -G CMake generator command line argument
---@field buildArgs? string[] An array of additional arguments to pass to `cmake --build`
---@field buildToolArgs? string[] An array of additional arguments to pass to the underlying build tool
---@field settings? {[string]:string} Table of parameters which will be passed as `-Dkey=value` to `cmake` command
---@field env? {[string]:string} Table of parameters which will be passed as environment variables to `cmake`
---@field linkage? "static"|"shared" Linkage type

---@class CMakeConfigCMakeTerminal
---@field split "left"|"right"|"below"|"above" Split direction
---@field size number Terminal's size in lines
---@field close_on_exit "success"|"failure"|boolean When to close termilal. `"success"` - after success, `"failure"` - after failure, `true` - always, `false` - never
---@field open_on_start boolean Open terminal when `cmake` starts
---@field clear_env boolean Do not pass shell environment to cmake process
---@field enter boolean Focus on opened terminal window

---@class CMakeConfigTargetTerminal
---@field split "left"|"right"|"below"|"above" Split direction
---@field size number Terminal's size in lines
---@field enter boolean Focus on opened terminal window
---@field immediately boolean Run command immediately. If false, command will just be pasted to terminal so you can modify it
