Perhaps a bit more detail will help :)

First, you can run make with VERBOSE=1 to check the exact compiler
command, and see the include paths actually used. It's strange that
OpenJPEG isn't found in your case, as the default search location is
under /usr, and since you have /usr/include/openjpeg.h that should be
enough.

Secondly, the top-level CMakeLists.txt file has a few OpenJPEG related
values:

option(WITH_IMAGE_OPENJPEG      "Enable OpenJpeg Support
(http://www.openjpeg.org)" ON)

...

if(WITH_IMAGE_OPENJPEG)
    if(UNIX AND NOT APPLE)
        set(OPENJPEG /usr)
        set(OPENJPEG_INC ${OPENJPEG}/include)
        set(OPENJPEG_LIB openjpeg)
        set(OPENJPEG_LIBPATH ${OPENJPEG}/lib)
    else()
        set(OPENJPEG ${CMAKE_SOURCE_DIR}/extern/libopenjpeg)
        set(OPENJPEG_INC ${OPENJPEG})
    endif()
endif()

If you don't need OpenJPEG support (don't know what it's used for) you
can set WITH_IMAGE_OPENJPEG to OFF:

~/blender-cycles-build$ cmake <cycles-source-dir>
-DWITH_IMAGE_OPENJPEG=OFF <other options you want to set>

But I see in your other reply that you already know this :)

HTH,
Paul
