Question about force inclusion with precompiled header

Hello everyone,

I am successfully using precompiled header in my project to speed up build times. I noticed while reading the documentation about target_precompile_headers the following:

The list of header files is used to generate a header file named cmake_pch.h|xx which is used to generate the precompiled header file (.pch , .gch , .pchi ) artifact. The cmake_pch.h|xx header file will be force included (-include for GCC, /FI for MSVC) to all source files, so sources do not need to have #include "pch.h" .

Is there a way to avoid the forced inclusion of the precompiled header? I am wondering if it is possible to avoid that in such a way that the source files that make use of the precompiled header explicitly have to #include "pch.h".

Thank you very much for any help or clarification.

Alex
