Probably a little bit of each...

Try putting a call to:
CTEST_READ_CUSTOM_FILES("${CTEST_BINARY_DIRECTORY}")

after ctest_configure and before ctest_build...

One could certainly make the argument that this should be entirely invisible
and automatic and buried inside the ctest_configure call. In that sense,
it's a bug.

I know the author of the ctest_read_custom_files command intended things to
be this way, but I still do not understand why... Perhaps if nobody can
explain why it should be left this way, it would make sense to try to make
this implied/automatic at the end of a ctest_configure command....


HTH,
David
