cygport: CYGCMAKE_SOURCE seems to have no effect.

[Carlo B.]

Hello,
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 "CYGCMAKE_SOURCE=${CYGCMAKE_SOURCE}"
echo "B=${B}"
echo "S=${S}"
echo "PWD=${PWD}"

and the result is:

CYGCMAKE_SOURCE=/cmake
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}.
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.

Sincerely.
