ccmToFoam and foamToCcm build error
the install location from makeCCMIO differs from what ccm/Allwmake for ccmToFoam and foamToCCm. So, Allwmake script failed to find libccm.so and compile ccmToFoam and foamToCCm.
I have a look at ccm/Allwmake script and etc/config.sh/ccm in OpenFOAM-plus source tree. Allwmake tries to find the library in $FOAM_LIBBIN but etc/config.sh/ccmio sets the library location to $WM_THIRD_PARTY_DIR/platforms/$WM_ARCH$WM_COMPILER/$ccmio_version
the value from ccmio script is close to $FOAM_EXT_LIBBIN but not exactly.
makeCCMIO in ThirdParty-plus tries to install to $WM_THIRD_PARTY_DIR/platforms/$WM_ARCH$WM_COMPILER which is set by the value defined in etc/tools/ThirdPartyFunctions and identical value by etc/config.sh/ccmio
I think Allwmake for ccmToFoam and foamToCcm should be modified to match the thirdparty library location to make to work the utilities for ccm.
