dnl Macro for checking availability of tests and coverage infra structure

dnl Usage: EFL_TESTS(profile)
dnl Valid profile are auto, tests, coverage, no
dnl Call PKG_CHECK_MODULES, AC_CHECK_PROG, define CHECK_CFLAGS/CHECK_LIBS and modify CFLAGS/LIBS
dnl It define EFL_HAVE_TESTS/EFL_HAVE_LCOV for use in Makefile.am
dnl It set have_test and have_coverage to yes/no depending if found
