Ubuntu build error: Could NOT find Qhull

[Sea421]

Hi team,

I am trying build from source in ubuntu by running scripts in scripts/linux folder.
But 1_build.sh gives following error :

Could NOT find Qhull (missing: QHULL_libqhull_LIBRARY libqhull)

I have installed qhull by:

sudo apt-get install libqhull*

But it still getting error.
How to fix it?

Thanks

The issue is not related to libqhull: when qhull is not found, the bundled source will be used.
The issue seems to be the cmake cache, just delete the build directory and try to run cmake again.
