CMake can't find Qt4 but then finds Qt4

I have the following in my CMakeLists.txt

find_package(Qt4 4.8.6 REQUIRED COMPONENTS Core)

target_link_libraries(debug Qt4::Core)

And I am getting the following error

Could NOT find Qt4 (missing: QT_CORE_INCLUDE_DIR QT_CORE_LIBRARY) (found
suitable version "4.8.6", minimum required is "4.8.6")

I ran dpkg -l | grep qt and I have libqt4-dev and which qmake returns /usr/bin/qmake.

Any ideas? I'm on Ubuntu if that helps.

Proper name for Qt4 "Core" component is QtCore. See e.g. this question as usage example.

The error message means that CMake has found QT4 partially: it has found basic libraries and include directories, but it has been unable to find things about "Core" component you ask. Note on CORE substring in missing variables' names.
