update CMAKE_PREFIX_PATH setting command (#134934)

Browse Source 
Current setting command of the `CMAKE_PREFIX_PATH` environment variable will overwrite values if it had already been set with some values. Changing it to `:` appends the conda env search path to its values to avoid library not found issues.
`export CMAKE_PREFIX_PATH=${CONDA_PREFIX:-"$(dirname $(which conda))/../"}:${CMAKE_PREFIX_PATH}`
