Force CMake to rebuild precompiled headers

How do I get CMake to rebuild all the precompiled headers? (Using g++ and Linux) And how do I get CMake to disable all precompiled headers?

I am getting some build errors that have sprung up and they refer to the .ch files. So want to investigate whether this is due to precompiled headers.

In CMake, and assuming use of the target_precompile_headers() command, you can disable precompiled headers for a specific CMake target by setting the DISABLE_PRECOMPILE_HEADERS property:

set_target_properties(MyTarget PROPERTIES 
    DISABLE_PRECOMPILE_HEADERS ON
)

or you can disable precompiled headers for the entire project by setting this in the top-level CMake file:

set(CMAKE_DISABLE_PRECOMPILE_HEADERS ON)

To get CMake to rebuild all of the precompiled headers, you could simply delete those that have been generated, so they are re-generated.
