This is not technically correct (the Boost dependency is introduced through
libcommon), but less invasive as it doesn't pull in libcommon on the linker
command line.
The opencascade patch intrusively checked against libraries but broke
some build scripts. This restores the default cmake OCE behavior that was
changed by 2bab30d9a and makes the OpenCascade search truly secondary.
