description:
add support for CMAKE_PKGSRC_BUILD_FLAGS

CMAKE_PKGSRC_BUILD_FLAGS
     If set to yes, disable compiler optimization flags associated
     with the CMAKE_BUILD_TYPE setting (for pkgsrc these come in from
     the user via variables like CFLAGS).  The default is yes, but you can
     set it to no for pkgsrc packages that do not use a compiler to avoid
     cmake "Manually-specified variables were not used by the project"
     warnings associated with this variable.
