# Hints for CMake noobs like me.
# this is your child project, the parent project is your "main"
# where you try to attach this lib

# CMake in your root project:

# set(MET "3party/media-editor-template")   # something like set variable, to get it write ${MET}
# add_subdirectory(${MET})

# set(SOURCE_FILES main.cpp)
# add_executable(${PROJECT_NAME} ${SOURCE_FILES})

# include_directories(${MET}/src)         # to find #include "..." do this
# target_link_libraries(${PROJECT_NAME} media-editor-template)  # undefined reference without this
