I have for Qt Creator itself the following:

-DCMAKE_PREFIX_PATH:PATH=%{Qt:QT_INSTALL_PREFIX};c:/llvm/msvc

The CMake documentation 
<https://cmake.org/cmake/help/latest/variable/CMAKE_PREFIX_PATH.html> 
states:

    Semicolon-separated list
    <https://cmake.org/cmake/help/latest/manual/cmake-language.7.html#cmake-language-lists>of
    directories specifying installation/prefixes/to be searched by
    the|find_package()|
    <https://cmake.org/cmake/help/latest/command/find_package.html#command:find_package>,|find_program()|
    <https://cmake.org/cmake/help/latest/command/find_program.html#command:find_program>,|find_library()|
    <https://cmake.org/cmake/help/latest/command/find_library.html#command:find_library>,|find_file()|
    <https://cmake.org/cmake/help/latest/command/find_file.html#command:find_file>,
    and|find_path()|
    <https://cmake.org/cmake/help/latest/command/find_path.html#command:find_path>commands.
    Each command will add appropriate subdirectories (like|bin|,|lib|,
    or|include|) as specified in its own documentation.

    By default this is empty. It is intended to be set by the project.

Cheers,
Cristian.
