fix include path in CMakeLists.txt

Sven Kipry · Sven Kipry · commit 83a006676014 · 2020-05-05T07:53:57.000+02:00
The include path is not set correctly when QHotkey is build as a
subproject. To fix that CMAKE_CURRENT_SOURCE_DIR should be used instead
of CMAKE_SOURCE_DIR in target_include_directories.
