Prefer openssl binary from the same location as the openssl library.
Make it possible to suppress certificate generation during install by
passing OPENSSL=: to make.
Use install-data-hook to ensure restrictive permissions on rsakeys.ini.
Don't create rsakeys.ini in init scripts. This makes xrdp functional upon
"make install" without relying on the init scripts.
Packagers should not package rsakeys.ini, it should be created when the
package is installed.
AM_CPPFLAGS is for flags passed to the preprocessor, such as defines and
includes. AM_CFLAGS is for flags affecting the compiler, such as debug
and optimization settings.
INCLUDES is an obsolete name. Users can pass INCLUDES and break
compilation. AM_CPPFLAGS is more explicit that the flags come from
Automake and should not be overridden.
