Conan Header Not Found: Header Exists in Package but Fails to Compile in CMake Project

I'm working with a C++ project using Conan for dependency management and CMake as the build system.

I created a new Conan package for a static library called mylib. The header files are located under the path:

mylib/include/mylib/MyHeader_Interface.h

relevant conan_pkg.py content looks like this:

from conans import CMake, ConanFile

@property
    def conan(self):
        return self._conan

def get_exports_sources(self) -> Iterable[str]:
    return (
        "src/**",
        "include/**",
        "cmake/*",
        "CMakeLists.txt",
        "version",
        "LICENSE",
        "tests/**"
    )

def package_info(self):
     super().package_info()
     self.conan.cpp_info.includedirs = [
     self.conan.cpp_info.rootpath + '/include/mylib']

Conan version 1.64.0

After creating the package, I confirmed the header is located at:

~/.conan/data/mylib/0.0.1/user/channel/package/<package-id>/include/mylib/mylib/MyHeader_Interface.h

In the consuming core project, I use:

find_package(mylib REQUIRED)
target_link_libraries(${target_name} PUBLIC mylib::mylib)

However, when compiling, I get the following error:

fatal error: mylib/MyHeader_Interface.h: No such file or directory

Question: Why is the header not found during compilation, even though the package seems to have it in the expected include path? Do I need to adjust the include directory layout or change how I reference the headers in the consuming project?
