Here, you should include something like:

comment "live555 needs C++ compiler"
	depends on !BR2_INSTALL_LIBSTDCPP

This allows the user to know that live555 is available, but not
selectable due to the lack of C++ support. We typically do that when a
package has a dependency on a toolchain option.

Our convention is to use $(BR2_PACKAGE_LIVE555_OPENRTSP), i.e
normal braces instead of curly braces.

You could do it a little bit differently:

LIVE555_FILES_TO_INSTALL-$(BR2_PACKAGE_LIVE555_OPENRTSP) += testProgs/openRTSP
LIVE555_FILES_TO_INSTALL-$(BR2_PACKAGE_LIVE555_MEDIASERVER) += mediaServer/live555MediaServer
LIVE555_FILES_TO_INSTALL-$(BR2_PACKAGE_LIVE555_MPEG2_INDEXER) += testProgs/MPEG2TransportStreamIndexer

And then your LIVE555_INSTALL_TARGET_CMDS would iterate over the
LIVE555_FILES_TO_INSTALL-y list, and install the corresponding
binaries. Need to be careful about the case where
LIVE555_FILES_TO_INSTALL-y is empty because no binary has been selected
for installation.
