Fix build when libccd package config not found.

[law12019]

Link to ccd library by full path per preferred cmake convention. This fixed the build when libccd is not found by pkgconfig.

In a similar vain, but using pkg-config, I use a FindCCD.cmake module in a project that depends on both ccd and fcl:

include(FindPackageHandleStandardArgs)
find_package(PkgConfig)
if(PKGCONFIG_FOUND)
    pkg_check_modules(CCD ccd>=2.0)
    if(CCD_LIBRARIES AND NOT CCD_INCLUDE_DIRS)
        set(CCD_INCLUDE_DIRS "/usr/include")
    endif()
endif()
find_package_handle_standard_args(CCD DEFAULT_MSG CCD_LIBRARIES CCD_INCLUDE_DIRS)

This has the added advantage that you can check for the appropriate libccd version.

Is this ready to merge?

I would prefer to use FindCCD.cmake as @mamoll suggested, but this looks good as a stopgap solution. Also, CCD_VERSION variable would be considerable to add to FindCCD.cmake as this.
