"privateincludedirs = -Isrc"
not needed, because "src" is current dir during compilation
"publicincludedirs = -Iinclude"
"AM_CPPFLAGS = -I${top_srcdir}/include"
"LD_LIBRARY_PATH="
not needed. Test binaries are built with RPATH
"test:"
"TESTS = test"
"check_PROGRAMS = test"
...
"test" stdout goes to "test.log"
