# utfcpp (UTF8-CPP) is a header-only C++ library -- the cmake build produces an
# INTERFACE target, so nothing is compiled into the main package and the shipped
# payload is the -dev headers under /usr/include/utf8cpp plus the find_package()
# cmake files under /usr/share/utf8cpp/cmake. There is no on-target C++ compiler
# to exercise the templates, so the on-target check is that every file the recipe
# installs is present and carries its real utfcpp content (the header guard and a
# defining API symbol), not an empty placeholder or a wrong file.

# The umbrella header and every utf8/*.h the recipe installs are present.

# the generated ConfigVersion.cmake reports 4.0.4 under utfcpp_4.0.5.bb.
