set(CMAKE_CXX_STANDARD 11)    
include_directories("${JAVA_HOME}/include ${JAVA_HOME}/include/linux")

link_libraries(${JAVA_HOME}/jre/lib/amd64/server/libjvm.so)

set(SOURCE_FILES
    main.cpp
    wrapper/WrapperJNI.cpp
    wrapper/WrapperJNI.h)

You can use the following example to solve your problem:

find_package(JNI)
    if (JNI_FOUND)
        include_directories(SYSTEM ${JAVA_INCLUDE_PATH})
        include_directories(SYSTEM ${JAVA_INCLUDE_PATH2})
    endif()

if (JNI_FOUND)
    target_link_libraries(<example> ${JAVA_JVM_LIBRARY})
endif()
