I think you can add a "depends on BR2_arm || BR2_armeb" here.

While tegracrm is a host tool and therefore can be built regardless of
the selected target architecture, it doesn't make sense to build it if
the target architecture is something else than ARM.

Please use the github helper function.

The license is actually BSD-3c + NVIDIA Software License it seems.

Are you sure this is sufficient? The configure.ac script checks for the
cryptopp library. The build might have worked on your system if you had
the cryptopp library installed system-wide.

Also, src/Makefile.am is doing the following nasty thing:

  AM_CPPFLAGS = -isystem /usr/include/$(CRYPTOLIB)

Such an hardcoded reference to /usr/include/$(CRYPTOLIB) is not going
to work if the cryptopp library gets built by Buildroot, since the
library headers will be in $(HOST_DIR)/usr/include and not
in /usr/include.

Best regards,

Thomas
