in addition to my previous message, I did some experiments with the
code of cygport and I added these lines to
/usr/share/cygport/cygclass/cmake.cygclass:

echo "B=${B}"
echo "S=${S}"
echo "PWD=${PWD}"

If you look at the Cygport Install Functions docs for docinto, ...into,
defining target directories, you would see that an "absolute" path
disables cygport from prefixing a subdirectory name with the package
name, etc. so CMakeLists.txt is (linked) under ${S,B}/cmake, and cygport
will automatically find that, so it should not be required or specified:
https://cygwin.github.io/cygport/cmake_cygclass.html#robo767
"This is only necessary when the top-level CMakeLists.txt is not in $S
and cygcmake is not being run in the same subdirectory of $B which under
$S contains the top-level CMakeLists.txt. (IOW if the top-level
CMakeLists.txt is in $S/unix and cygcmake is run from $B/unix, setting
CYGCMAKE_SOURCE would not be necessary.)"
as cygport would find CMakeLists.txt in $S/cmake/ so it would copy or
link those under $B, and run cygcmake under the equivalent subdirectory.
B=/home/carlo/liblo.src/liblo-0.31-1.x86_64/build
S=/home/carlo/liblo.src/liblo-0.31-1.x86_64/src/liblo-0.31
PWD=/home/carlo/liblo.src/liblo-0.31-1.x86_64/build
*** ERROR: cygcmake: cmake directory not found
But ${CYGCMAKE_SOURCE} was set as:
CYGCMAKE_SOURCE="${S}/cmake"
So, it seems to me that there is at least a bug into the
documentation, because ${CYGCMAKE_SOURCE} does not seem to allow the
use of {S}.
CMakeLists.txt is found automatically by cygport if it is under $S, as
that is the documented assumption (see above).
I was able to make it working by writing:
CYGCMAKE_SOURCE="$(pwd)/${NAME}-${VERSION}-${RELEASE}.${ARCH}/src/${NAME}-${VERSION}/cmake"
but I don't know if this is the right way to do it and could be accepted or not.
