I hope I'm doing it right this time

Thanks Ian, the Makefile works and now I understand how to keep the Graph_lib files on a different path

Thank you Albrecht,  but the CMAKE_PREFIX_PATH doesn't seem to change the default, which remains /usr/local/include and /usr/local/lib:
Here are Ian's checks:

   /home/ken01/repos/fltk-1.4.0/build/bin/fltk-config --version
    /home/ken01/repos/fltk-1.4.0/build/bin/fltk-config --cxxflags

    /home/ken01/repos/fltk-1.4.0/build/bin/fltk-config --ldflags
    -L/usr/local/lib -lfltk -lm -lX11 -lXext -lpthread -lXinerama -lXfixes -lXcursor -lXft -lXrender -lm -lfontconfig -ldl

    /home/ken01/repos/fltk-1.4.0/build/bin/fltk-config --includedir

I tested a couple of variants and find out that CMAKE_INSTALL_PREFIX changes the default /include and /lib path
cmake -D CMAKE_INSTALL_PREFIX=/home/ken01/repos/fltk-1.4.0/build -D 'CMAKE_BUILD_TYPE=Debug' -D FLTK_BUILD_EXAMPLES=ON ..
with the result:

     /home/ken01/repos/fltk-1.4.0/build/bin/fltk-config --cxxflags
     -I/home/ken01/repos/fltk-1.4.0/build/include -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -D_THREAD_SAFE -D_REENTRANT

    /home/ken01/repos/fltk-1.4.0/build/bin/fltk-config --ldflags
    -L/home/ken01/repos/fltk-1.4.0/build/lib -lfltk -lm -lX11 -lXext -lpthread -lXinerama -lXfixes -lXcursor -lXft -lXrender -lm -lfontconfig -ldl

    /home/ken01/repos/fltk-1.4.0/build/bin/fltk-config --includedir

But there's no "include" folder in fltk/build
So I created one, where I moved the FL folder with both abi-version.h and all the .H files
I'm not sure if it's the right thing to do, but now it works, the Makefile finds the path to FL and libs.

I tried also like below, but the default path remains /usr/local/include and usr/local/lib

cmake -D CMAKE_INCLUDE_PATH=/home/ken01/repos/fltk-1.4.0 -D CMAKE_INCLUDE_PATH=/home/ken01/repos/fltk-1.4.0/build/ -D CMAKE_LIBRARY_PATH=/home/ken01/repos/fltk-1.4.0/build/lib 

Thank you all, I finally have something that works :)
