Hi @wizard-123
Thanks for your question.
When defining components
, most of the global values are dropped, they are not additive (we have tried, but it would have been breaking behavior, so we couldn't move it forward), so only the components values are taken into account.
So if all components for example want to define the include directories as "inc", they have to do self.cpp_info.components["compX"].includedirs = ["inc"]
for every component, the self.cpp_info.includedirs
is discarded and not used.

Thank you for your answer, but I am still confused about why the cmake enviroment variable CMAKE_PREFIX_PATH is set to the component‘s .builddirs instead of the root’s .builddirs during the configuring process of the test package.
from conan.
self.cpp_info.set_property("cmake_find_mode", "none")
self.cpp_info.builddirs = [f"lib/cmake/vtk-9.3"] # This doesn't have effect, it is discarded
self.cpp_info.components[full_name].builddirs.append("lib") # Only this one has effect
Line 2 doesn't have any effect, once components are defined, the only definition that counts is the components one in Line 3. Does this clarify the issue?

Thank you very much for resolving my question
