cmake set subdirectory options
cmake
Solution
CMake's `option` command more or less adds a boolean variable to the cache.
If you want to override the default value of an option, simply add a variable of the same name to the cache yourself before pulling in the subproject:
set(WITH_FUNCTION_X OFF CACHE BOOL "enable X functionality")
add_subdirectory(subproject)
Note that the `set` command does nothing if there is already a value of that name in the cache. If you want to overwrite any existing value, add the `FORCE` option to that command.
Sample with `FORCE`
set(WITH_FUNCTION_X OFF CACHE BOOL "enable X functionality" FORCE)
add_subdirectory(subproject)
Problem
Is there anyway to set the options of a subdirectory? So I have a project that depends on a subproject, the subproject has an option: ``` OPTION(WITH_FUNCTION_X "enable X functionality" ON) ``` And in my parent project I want to include the subproject, but without functionality X. thanks!
