With vcpkg portfile, how to insert regular CMake command?

I'm trying to customize a lib installed through vcpkg with regular CMake commands. The only thing I need to tweak is to enable a preprocessor, e.g., BUILD_WITH_THIS_OPTINAL_FEATURE.

With Visual Studio, it's pretty straightforward: Just add it to the C/C++ > Preprocessor property of the project. But with vcpkg, it's unclear how to mix it with its own functions.

Say if I have a portfile ready under

E:\_dev\vcpkg\ports\mylib\portfile.cmake

I'd really love to let it know that I want to

add_compile_definitions(BUILD_WITH_THIS_OPTINAL_FEATURE)

But doing so directly in portfile.cmake gives me

CMake Error at ports/mylib/portfile.cmake:38 (add_compile_definitions):
  Unknown CMake command "add_compile_definitions".

Anyone knows how?

Solved it myself.

I just need to add the following to vcpkg_configure_cmake's OPTIONS input arg

-DBUILD_WITH_THIS_OPTINAL_FEATURE=ON
