When I build Coin-4.0.0 using configure under MacPorts, I get

/opt/local/Library/Frameworks/Inventor.framework/Versions/D/Libraries/libCoin.80.0.0.dylib
/opt/local/Library/Frameworks/Inventor.framework/Versions/D/Libraries/libCoin.80.dylib
/opt/local/Library/Frameworks/Inventor.framework/Versions/D/Libraries/libCoin.dylib

while there is no such directory when building with cmake with

configure.args-append \
-DCOIN_BUILD_MAC_FRAMEWORK=ON \
-DCMAKE_INSTALL_PREFIX=${frameworks_dir}

all other files are installed correctly.

This is a blocker when trying to build SoQt, py-pivy and FreeCAD, as they are looking for the .cmake files.
